In contrast to alternating current, or AC, which, depending on the supply's frequency, switches direction 50 or 60 times per second, the current in DC circuits flows only in one direction.

In the meanwhile, the main switch does not require shunt capacitors, so there is no resonant current in the main switch. In addition, during the zero-voltage notch, the resonant current also does not ...
