| Abstract: | This article builds the orthogonal two-phase winding and the DC voltage to link the center of the electro-magnetic stirring power source main circuit.The IGBT used number which in the circuit is half of which in two-phase IGBT bridge circuit.Based on bipolar SPWM modulation,the paper proposes positive and negative output current IG-BT logic block to open pulse width modulation(LPWM) method,which has a switch for the gate to reduce consumption and improve the PWM switching frequency and the anti-through the ... |
