谐振IGCT软开关：零电压开关还是零电流开关？

In the last thirty years, the integrated gate-commutated thyristor (IGCT) has been employed in medium voltage $\,\mathrm{M}\mathrm{W}$ power level converters and has demonstrated some of the lowest conduction losses of any actively controlled device in traditional hard-switched, sub-$\,\mathrm{k}\mathrm{Hz}$ applications. Extending the use of the device to medium frequency applications, such as dc...
