3 Functional areas of the DC-DC converter

Figure 7. Functional areas of the STEVAL-DPSLLCK1 kit

The input DC voltage charges input capacitors C36 and C37. The primary side switches Q5, Q6, Q7, and Q8supply a square voltage waveform between –Vin and +Vin at the applied switching frequency to the resonant tankcircuit, with capacitors C39, C110, C130 and the leakage inductance of the main transformer T3.The full bridge on the primary side of the converter is based on STW70N60DM2 MDmesh DM2 Power MOSFETs;these high voltage switches are driven two-by-two (Q5-Q7 and Q6-Q8) with 50 percent PWM duty cycle and anappropriate dead time.As the approximately sinusoidal resonant tank current always lags the voltage waveform (inductive region), theMOSFET output capacitance has time to discharge during the dead time before the next turn-on, and achievezero voltage switching (ZVS).On the secondary side of the transformer, the input voltage waveform is rectified by the synchronous rectifierSTP310N10F7 MOSFETs with STripFET F7 technology (Q1, Q2, Q3, Q4, Q9, Q10, Q11, and Q12 in full bridgeconfiguration and two-by-two in parallel) and smoothed by output capacitors.A synchronous rectification (SR) technique is used to turn on the channel of low voltage MOSFETs instead of theinternal body diode, reducing conduction losses. The adaptive algorithm further reduces diode conduction timeand improves converter efficiency.PWM switching frequency control is used to regulate the voltage gain of the resonant tank and keep the converterin the inductive region. This allows ZVS over the entire operating range and reduced switching losses.To reduce driver and switching losses under light loads, the microcontroller manages burst mode operation byskipping some PWM pulses in a defined burst interval, but continuing to control the output voltage.L6491 gate drivers IC2 and IC3 drive the primary side switches, while gate drivers IC1 and IC4 drive thesecondary side SR MOSFETs.A current sensing circuit monitors the resonant tank current to provide overcurrent protection. The circuit consistsof a current transformer (CT) T2 and a small signal diode rectification bridge.The CS1 Hall Sensor monitors output current for output overcurrent protection, burst mode control, synchronousrectification and fan speed modulation.An auxiliary power supply circuit based on the VIPER27HD in flyback configuration supplies the primary side andsecondary side gate drivers, the primary side optocouplers (for PWM driving and bus voltage sensing), and thecontrol board, which receives 5 V through the DSMPS connector.

UM2348 - Rev 3 page 7/38

Finally, a small buck circuit (Q13, L3, D61 and C132) regulates the 48 V output voltage to supply the mounted fan.Q13 is driven by the microcontroller through a 10 kHz auxiliary PWM signal and a duty cycle that is variedaccording to the load current. The fan can also be supplied externally through the J5 connector.

4 System setup and operation

4.1 Board and cable connectionsThe evaluation kit can manage up to 3 kW of power across the operating input voltage range. To performfunctional and efficiency testing, you can use the following equipment:• A 3200 W programmable DC voltage source up to 450V 10A max• 60 V/65 A DC electronic load• Power analyzer (optional)• Digital oscilloscope (optional)

Step 1. Connect the programmable DC voltage source to J2 with cables, or to B1 and B2 with bus bars.The output load must be connected to the J3 connector with a cable of appropriate cross-section tocarry the desired load current (63 A max).

Note: Always connect the earth to the J2 connector.Step 2. The on-board cooling should always be enabled; ensure that it is not disconnected as this may provoke

system damage from overheating.– To perform efficiency measurements without fan consumption drawn from the output, remove

jumper J4 and apply an external voltage (up to 48 V, 240 mA) to the J5 connector.– You can also disable on-board fan control in the FW or via the UI, but remember to remove J4

before applying the external voltage.Step 3. Ensure that the STEVAL-DPSLLCP1 power board is not powered.Step 4. Connect the STEVAL-DPS334C1 digital control board to the STEVAL-DPSLLCP1 power board through

the 64 pin DSMPS connector P1.The control board in the kit is already programmed and ready to use, you do not need to load firmware.To program a new control board, you should power it with an external 5 V supply through the J3connector on the control board

Note: Do not connect the control board to the power board for this operation.Step 5. To update or debug the FW, connect a 10 wire flat cable to J7 on the control board and J1 on the

adapter board.Step 6. Connect a standard programmer (like ST-LINK or J-Link) through the J3 standard 20 pin JTAG

connector on the adapter board.

Note: Do not apply any voltage to the power board for these operations.

Figure 8. STEVAL-DPSLLCK1 connection scheme

4.2 Board useThe auxiliary power supply supplies the control board, drivers and signal conditioning circuitry once the inputvoltage rises above 100 V. The presence of the input voltage is signaled by the red LED D64 on the power boardand the green LED D1 on the control board.While the input voltage remains above 100 V, but below 375 V, the system is in an input undervoltage state inwhich you can safely reprogram the microcontroller using IAR Embedded Workbench for ARM ver.7.80 or higher,or any other appropriate programming tool.When the input voltage is raised to the required 375 V to 425 V input voltage range, the converter becomesoperational after a default wait time of 1000 ms.To avoid high current spikes a board start up, a ramp-up procedure is implemented. In this procedure, the highvoltage MOSFETs are driven at the maximum switching frequency of 380 kHz, which decreases linearly to theminimum 120 kHz value over 500 ms.If the output voltage reaches the reference 47 V value during ramp-up, the PI control loop is closed and thesystem commences normal operation. If the ramp-up time expires before the nominal voltage is reached, astartup failure is triggered and PWMs are stopped.The blue LED D2 on the control board shows the state of the converter:• off when the system is off• slow blinking while the system is idle• rapid blinking during ramp-up• on during normal operation

During normal operation, the system implements burst mode and synchronous rectification techniques to increaseconversion efficiency.The evaluation kit includes the following protections:• Input overvoltage and undervoltage• Output overvoltage and undervoltage• Fast overcurrent• Output overcurrent

UM2348 - Rev 3 page 10/38

• Over temperature• Startup failure

Each fault is identified with a code and the system fault variable is then given by an OR operation of the codes ofall the faults that have occurred. When a fault occurs, the PWM signals are stopped and the microcontroller setsthe converter to the FAULT state. In this state, the blue status LED D2 is off and the red fault LED D3 blinks acertain number of times to indicate the type of fault that occurred. The blinking rate also indicates fault type:• voltage-related faults: tON = 500 ms, tOFF = 500 ms• other faults: tON = 250 ms, tOFF = 250 ms

All blinking sequences are repeated after three seconds.Input undervoltage and overvoltage faults are automatically cleared when the input voltage returns to within thecorrect operating range. To clear other faults, you must use the user interface or disconnect the input voltage andwait until the unit shuts down.

5 User serial communication

The STEVAL-DPSLLCK1 kit can operate without the User Interface (UI), as the default FW automatically activatespower conversion when the input voltage enters the correct operating range.The User Interface is based on RS-232 serial communication and provides a simple way to set some real-timecontrol parameters, enable and disable driving signals, and read sensed values without changing the default FW.To use the UI, connect a RS-232/USB adapter between the DSMPS adapter board and your PC. Use acommunication tool like HyperTerminal to send command strings and read feedback messages from the system.The default communication parameters are listed below:• Baud Rate: 57600• Word Length bit: 8• Stop bits: 1• Parity: none• Flow control: none

The following commands can be sent in real-time while the application is running:• Start or stop voltage regulation• Enable or disable open loop mode• Enable or disable SR driving• Enable or disable adaptive SR• Enable or disable burst mode for light load operation• Enable or disable fan driving• Set or get PWM frequency (in open loop mode)• Set or get PWM dead time• Set or get SR delays (when adaptive SR is not active)• Set or get voltage PI regulator gains• Read monitored values (VIN, VOUT, IOUT and heat-sink temperature)• Get and clear last fault occurred• Read configuration parameters• Get FW and UI version

The frames that can be sent to the system are help frames, command frames, set frames and get frames.Help frames give information regarding FW and UI versions, and the syntax of each frame category:• - COMMAND FRAME:

– <COMMAND_ID> <STATE>• SET FRAME:

– <SET_PARAM_ID> <NUM_VAL>• GET FRAME:
