高電圧GTOバルブに適用可能なゲート電力供給回路方式 Novel Gate Drive Power Supply Circuit for High Voltage GTO Valves
In this paper, we propose a novel gate power supply circuit for high voltage GTO valves. The main feature of our circuit is the configuration itself that a power supply circuit is integrated into a snubber circuit of each GTO. A part of energy stored in a snubber capacitor is transferred to a power supply capacitor and the transferred energy is provided for a gate drive circuit. A concrete design of our circuit is represented according to a gate drive power which is necessary for each of series-connected GTOs. We verify the availability of our circuit using several successful simulation and experimental results.
