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.
However, the pulse characteristics are limited by the energy stored in the capacitor bank and on the performance and power dissipated in the switches and also on the rate of charge of Cdc. The energy initially stored in the Cdc capacitor is (18.69) if the S off time, T – ton, is enough for the PS Vdc to charge Cdc.
The regulation of the output voltage is also improved with the pulse train because the energy is passed to the energy storage capacitor as small packets. Common control techniques such as pulse width modulation can be used to control the size of the energy packet.
This means that after the pulse, the energy stored in the Cdc capacitor is 220 J, corresponding to a final pulse voltage of 19.149 V that is 4.2% voltage droop. Finally, the PS Vdc must recharge the 20 J and 4 J (i.e., 10% losses) in T – ton = 625 μs, and then, 18.4.1.2. Ground Switch
Pulsed power, PP, can be considered as the science and technology of accumulating electric energy over a relatively long period of time, followed by the subsequent energy release in very short pulses, a single one or a controlled repetitive sequence, thus increasing the instantaneous peak power.
