| Abstract |
This paper presents the study of the gate circuit of the bipolar pulsed power modulator. In order to output a high voltage bipolar pulse, the modulator has a modular structure in which a full bridge sub-modules are stacked in series. The gate circuit is designed to operate the discharge switch of the sub-module through a simple structure. The entire gate circuit is driven by a signal from a pair of control loops connected through a transformer. The operation of the designed gate circuit is divided into four operating modes according to the input signal and analyzed in detail. The gate signals according to the change of circuit parameters are confirmed by a result of PSpice-based simulation modeling. Testing circuit consisting of top and bottom switches are implemented, and the basic operation is verified by gate drive experiments. |
