【 摘 要 】

In the reversely switched dynistor (RSD) -based pulse power circuits, a magnetic switch is usually necessary to be applied together with a main switch. It occupies space and needs a magnetic reset. In this paper, a method of designing a RSD-based pulse circuit without a magnetic switch is proposed. In the pulse circuit, a RBDT (reverse blocking diode thyristor) is used to separate the two capacitors and provide an energy branch. The pre-charge time of the RSD can be guaranteed by the energy conversion between the capacitors and inductors, instead of the saturation of the magnetic switch. In addition, the energy which is reused to trigger the RSD is based on an inductor. The pulse circuit is evaluated by simulations and practical experiments. According to the experimental results, the factors affecting the load pulse current and triggering of the RSD and RBDT are studied. Meanwhile, a method to reduce the current in the trigger switch, which is a potential problem in the pulse circuit, is proposed.
