When simulating complicated switching converters like 3-phase PFCs, you want to ensure the selected SPICE models of the SiC transistors are doing the right job. There is nothing more frustrating than a long simulation ending with wrong waveforms because the models were bad. This article shows how a simple double-pulse test can let you check if a given SPICE model is faithfully matching the data-sheet parameters or, on the contrary, needs to be replaced by another subcircuit model.

High-voltage electrolytic capacitors are familiar components in the power conversion landscape. Often used for filtering applications, they undergo a permanent stress due to the circulation of rms current. It is therefore important to determine this heating contributor and choose a capacitor type offering adequate design margins. This article gives some hints on how to select the right capacitor.

The flyback converter is a popular switching structure found in consumer appliances but also in industrial products. Either used as a main converter or as an auxiliary power supply, it can be supplied from a low- or high voltage dc rail. The converter is simple to build with its single switching transistor and lends itself well to producing cost-effective power supplies from a few watts to 100-150 W roughly.

This article explores the control of magnetizing current in Dual Active Bridge (DAB) converters to prevent transformer saturation. Innovative techniques eliminate the need for bulky dc-blocking capacitors, enhancing efficiency and reliability while reducing system costs. The methods presented offer new pathways for optimizing modern power supply systems.
