Abstract
Conventional dc power supplies operate at a given dc output voltage into a constant or near constant load. Recharging the capacitor voltage to a specified voltage is tasked to a capacitor charging power supply (CCPS). The charging mode ends when the capacitor voltage equals the output voltage of the power supply. The capacitor is continually refreshed by the power supply. During the discharge mode, the charging resistor isolates the power supply from the pulse load. The poor efficiency when charging a capacitor through a resistor from a high-voltage power supply limits its application to low charging rates. In the resonance-charging concepts, the energy is transferred to the load capacitor in a single pulse, and it is not possible to compensate for capacitor leakage. When the MOSFET is turned on, current increases in the primary winding, storing energy in the magnetic field. When the primary current reaches zero and starts negative, the diode turns on, which allows the MOSFET to be turned off efficiently at zero current.
