switched power supply
101импульсный 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… …
