摘要： PROBLEM TO BE SOLVED: To protect a self-turn-off element from a large current change generated at turn-on without using an arm reactor, and to regenerate a snubber energy to a main circuit and reduce a snubber loss. SOLUTION: The power converter has a main switching circuit series-parallel connecting a plurality of main switches to a DC power supply and snubber circuits connected in parallel with each main switch. The power converter has also auxiliary resonance circuits using parts of the main switching circuit and parts of the snubber circuits to form one path. The auxiliary resonance circuit turns a current and a voltage between both ends of the main switch to zero by discharge in the auxiliary resonance circuit, and the snubber energy of the snubber circuit is regenerated by a resonance circuit. A voltage rise at the turn-on is avoided without using the arm reactor by turning the current and the voltage between both ends of the main switch to zero by discharging the auxiliary resonance circuit. The surge of a DC voltage at the turn-off by the arm reactor is reduced, and the capacitor capacity of the snubber circuit is decreased by reducing the effect of a voltage surge.

摘要翻译：要解决的问题：为了保护自关断元件免于在导通时产生的大电流变化而不使用臂式电抗器，并且将缓冲能量再生到主电路并减少缓冲器损耗。电源转换器具有将多个主开关并联连接到与每个主开关并联连接的直流电源和缓冲电路的主开关电路。功率转换器还具有使用主开关电路的部分和缓冲电路的部分的辅助谐振电路以形成一个路径。辅助谐振电路通过辅助谐振电路中的放电使主开关的两端之间的电流和电压变为零，并且缓冲电路的缓冲能量由谐振电路再生。通过将辅助谐振电路放电，将主开关的两端之间的电流和电压转换为零，就可避免接通时的电压上升。通过臂式电抗器关闭的直流电压的浪涌降低，并且通过减小电压浪涌的影响来减小缓冲电路的电容器容量。版权所有（C）2010，JPO＆INPIT
