Abstract :
A kicker power supply with repetition rate of 1 kHz was designed and constructed. Since a conventional thyratron switch cannot be operated with a sufficient lifetime in such a high repetition rate, a new type of a power supply has been developed that employs high power IGBTs as switching modules. In order to realize a simultaneous turn-on of numerous IGBTs connected in parallel and in series, a new technology, a subordinated-driving method, is applied. With this new type of the power supply, a kicker field with a repetition rate of 1 kHz is achieved. The power supply is proved to function with sufficient stability and its jitter is found to be small, within ±1 nsec
