Uittreksel

A novel circuit topology of a fast 30 kV resonant capacitor charger is presented in this paper. The charger is designed for high repetition rate spark gap based pulsed power modulators. A spark gap can fire spontaneously (pre-firing) during charging of a capacitor bank due to poor dielectric recovery. The resulting near short circuit of the output can be handled repetitively by the circuit. A 15 kW prototype has been built and experimental results are presented. The charger is capable of charging a 8.4 nF capacitor to 30 kV in 35 μs with 91 % efficiency. The maximum repetition rate of this 3.8 J/cycle charger is 5 kHz. An active reset circuit for resetting of the pulse transformer core has been implemented. This circuit is also capable of recovering a large part of the energy which is stored in the stray capacitance of the secondary pulse transformer winding. A numeric simulation tool based on state space modeling is used to simulate circuit behavior. Measurements and simulations are in good accordance. A control loop is implemented to regulate the output voltage. The control scheme features a look up table which is dynamically updated to correct instabilities generated by random pre-fire events.
