| Abstract: | A shunt PFC technology which is shunted between the power supply and the load is proposed.Shunt inverter with frequency-doubling carrier phase shifted SPWM technique is used as the main circuit structure to reduce the device currents rate and switch stress and enhance the equivalent switch frequency.The phase angle of the source current reference is determined by the source voltage,while the magnitude of that is obtained from controlling the DC side capacitor voltage of the inverter.The PFC is realized by i... |
