How to choose Duty Cycle value for a Full-Bridge DC/DC Converter
I've noticed that while designing DC/DC converters, some sources (at the bottom of the website, comment of Benjamin Lough) suggest a "rule of thumb" duty cycle of 70%, while others (This is ...

How is soft switching in a PMSM inverter achieved?
Recently I found some papers about PMSM drives that use the regular circuit of 6 e.g. IGBTs to drive a permanent magnet synchronous motor but with a resonant circuit in front of it to achieve zero ...
