| Abstract: | In the paper,four stages equivalent circuits of starting process to medium-frequency power are established.It is analyzed that the variation of load has an influence on medium-frequency power starting circuit of inverter SCR in parallel. Relations between the circuit parameter of the stages with the SCR of activity and shutoff are established. Based on the principle of load starting in charge magnetism,the method is proposed,in which the medium-frequency power of parallel inverter SCR can be started reliably.And then,a design method of assist circuit parameter for the inverter SCR in parallel is proposed. For an example with PSpice simulation experiment of 500kW/1kHz parallel inverter medium-frequency power,the correctness of the method is tested and verified. |
