voltage source inverter by self-commutation 自换流式电压型逆变电路
In the source commutation technique, a commutating Thyristor is turned off byforcing the DC link current to zero.
在来源换向技术， 一台换向的可控硅整流器被关闭当换向发生时，潮流是近似地恒定的除了山谷。
To set up a sync point coincide with a natural commutation point in OTC products, and will be able to improve reliability and stability of the phase shifting trigger and output of the power source.
OTC有关产品把同步点设计在自然换相点上，使同步移相触发和电源输出更趋稳定可靠。
Since the utility model adopts the normalized full-bridge commutation, the power factor flowing to the electrical source system is 1, and the current can be reduced greatly.
且本实用新型由于使用了归一化的全桥整流，故此流向电源系统的功率因数为1，电流将会大大下降。
