Commutation cell, power converter and compensation circuit having dynamically controlled voltage gains
The present disclosure relates to a commutation cell configured for limiting switching overvoltage. The commutation cell includes a power electronic switch having a parasitic emitter inductance through which a voltage is generated upon turning off of the power electronic switch. The commutation cell...

| description | The present disclosure relates to a commutation cell configured for limiting switching overvoltage. The commutation cell includes a power electronic switch having a parasitic emitter inductance through which a voltage is generated upon turning off of the power electronic switch. The commutation cell also includes a dynamically controlled compensation circuit connected to the parasitic emitter inductance. The compensation circuit applies a controllable portion of the voltage generated through the parasitic emitter inductance at turn-off of the power electronic switch to control the voltage generated through the parasitic emitter inductance. A power converter comprising a pair of commutation cells and a compensation circuit of the commutation cell are also disclosed.
本公开涉及被配置用于限制切换过压的换向单元。该换向单元包括电力电子开关，具有寄生发射极电感，在该电力电子开关关断时，通过该寄生发射极电感生成电压。该换向单元还包括与该寄生发射极电感连接的动态控制的补偿电路。该补偿电路施加在该电力电子开关关断时通过该寄生发射极电感生成的电压的可控制部分，以控制通过该寄生发射极电感生成的电压。还公开了包括对换向单元的电力变换器和该换向单元的补偿电路。 |
