1kW Three phase boost converter
Three phase boost converter (section I : AC to DC rectifier)
PET-PHD project
CH1 : Voltage waveform of Vds, CH2: Output voltage of Boost Converter
CH1: Vds pk –pk = 620VCH2: Vout = 691.7V
PET-PHD project
ANSYS: Simplorer ( Electrical Circuit Simulation), Maxwell( Magnetic components), PCB layout( Q3D). Following sections are my studies on this tool
PET-PHD project
Case study: Boost inductor Core geometry: Toroidal coreMagnetic material : Power Ferrite Copper winding: Two turns
Simulation tool : Maxwell 3DPET-PHD project
High frequency winding resistance in terms of skin and proximity effect against operation frequency
PET-PHD project
Case study: Air –gapped boost inductor Core geometry: Toroidal core with air gapMagnetic material : Power Ferrite Copper winding: Two turns

High frequency winding resistance in terms of skin and proximity effect against operation frequency
PET-PHD project
Advantages: 1. High frequency copper winding loss in terms of skin
and proximity effect2. Determine self and mutual inductance of individual coil3. Determine winding loss in terms of non-sinusoidal
waveform ( time-vary large signal e.g. inductor current travelling inside boost inductor)
4. Determine winding and core loss in terms of non-linear magnetic materials( e.g. User can define magnetic materials by BH curve)
