Energy storage capacitors may be charged utilizing the same power electronic technology that has been applied in switching converters for constant power loads. Instead of charging the energy storage capacitor with a single pulse, switching converters can charge the capacitor with a series of pulses or pulse train.
Instead of charging the energy storage capacitor with a single pulse, switching converters can charge the capacitor with a series of pulses or pulse train. The peak current is reduced when charging with a series of pulses, thus improving the efficiency of the charging process.
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 advantages of this technique are its simplicity, reliability, and low cost. FIGURE 21.3.
Typically, this energy is stored in a capacitor and then released into the load. The rate at which the capacitor is charged and discharged is called the repetition rate, T, and may vary from 0.01 Hz for large capacitor banks to a few kHz for certain lasers.
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 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.
