FUG HCK 20000M-1000 Capacitor Charging Power Supply

The capacitor charging high voltage DC power supplies are designed specifically to the requirements of capacitor charging or capacitor conditioning, i.e. they have a more heavily designed output resistor to with-stand a pulsed load and a regulating circuit, optimized for fast switching over between current and voltage regulation and vice versa.

In principle, the rectified line voltage drives a square wave generator of fixed frequency, whose AC voltage is trans-formed, rectified and filtered, producing the output voltage. For regulation, the square wave voltage is pulse width modulated.
