51Commutation cell — The commutation cell is the basic structure in power electronics. It is composed of an electronic switch (today a high power semiconductor, not a mechanical switch) and a diode. It was traditionally referred to as a chopper, but since switching… …
52импульсный источник электропитания с коммутацией тока на первичной стороне — In primary switch mode power supplies, the AC mains voltage is first rectified and smoothed and then chopped ("switched"). Chopping means that the DC voltage is switched periodically at a frequency of 40 to 200 kHz using a power… …
