Abstract
A system for charging a capacitor with relatively high energy pulses at a relatively high pulse repetition rate includes a voltage transformer. A resonant circuit is established having an inductor connected to the transformer's low voltage side and a capacitor connected to the transformer's high voltage side. A power supply cooperates with a switch assembly to generate a train of pulses, alternating in polarity, in the circuit. With this arrangement, the transformer core is reset after each pulse. A rectifying circuit operates on the alternating polarity pulses to create a train of constant polarity pulses for charging the capacitor. For the system, the maximum charging voltage is regulated by a control circuit having a probe for measuring the voltage across the charging capacitor. This measured voltage is used by the control circuit to selectively operate the switch assembly and regulate the maximum voltage across the capacitor.
