• Simultaneous Writes to Registers: Simultaneous writes to registers in multiple PWM modules

• Event Trigger Enhancements: Support for up to 15 events

• Action Qualifier Registers: Shadowing of AQCTLA and AQCTLB registers

• CBC Trip Action: Additional options to clear CBC trip

Disastrous!!!

In multi-phase frequency modulated topologies,

period, duty and phase must all be updated at a

single point. Update delay between channels can be

disastrous. Multiple registers in different PWM

modules can now be configured to update on the

same trigger.

Global & One Shot Reload

In multi-phase applications which use a fixed phase,

frequency updates must be synchronised across

PWM modules. A single register write can now be

applied simultaneously across multiple modules.

Valley Switching

• Soft-switching technique that improves system efficiency and performance

• Switch should be turned ON when current through it is zero, at the valley of the voltage across it

Challenges

• Resonant oscillations are highly dependent on circuit parasitics and on operating conditions – making it difficult to detect optimum valley point


Valley Switching Enhancements

• A hardware mechanism to precisely control PWM ON/OFF time instants to implement valley switching

• Captures time period of oscillations to accurately delay PWM switching instant

• Ability to add software programmable offset to captured delay

• Programmable number of edges before the delay takes effect

• Multiple choices of triggers and events

• Allows easy adaptability for optimum performance under changing system/operating conditions

Switching Transients

PWM switching edges often produce "glitches" on the measured current signal which

in turn can cause spurious PWM tripping. In this scenario the converter cannot start

Software Frequency Response Analyzer

35

The Software Frequency Response Analyzer (SFRA) can measure the frequency response of the

control loop without disrupting normal operation.

The presence of the injected frequency is detected at various points in the loop and its magnitude

and phase measured as the frequency is swept between specified limits. Plots of gain and phase

vs. frequency can then be constructed from the collected data.
