摘要： A method for providing non-resonant zero-voltage switching in a switching power converter. The switching power converter converts power from input power to output power during multiple periodic switching cycles. The switching power converter includes a main switch and an auxiliary capacitor adapted for connecting to the main switch, and an inductor connectible to the auxiliary capacitor. When the main switch is on, a previously charged (or previously discharged) auxiliary capacitor is connected to the main switch with auxiliary switches. The main switch is switched off with zero voltage while discharging non-resonantly (charging) the auxiliary capacitor by providing a current path to the inductor. The auxiliary capacitor is disconnected from the main switch. The voltage of the auxiliary capacitor is charged and discharged alternatively during subsequent switching cycles. The voltage of the auxiliary capacitor stays substantially the same until the subsequent turn off of the main switch during the next switching cycle with substantially no energy loss in the auxiliary capacitor.

摘要： A circuit for converting a direct current voltage into an alternating current voltage includes a buck converter, a resonant DC voltage/DC voltage converter, a DC voltage/AC voltage inverter, and a DC link capacitor. The buck converter generates a DC current according to an input voltage generated by a voltage source operating at an optimal operation point. The resonant DC voltage/DC voltage converter converts the input voltage to a DC voltage according to a switch clock and a resonant frequency determined by a resonant capacitor and a resonant inductance of the resonant DC voltage/DC voltage converter. The DC voltage/AC voltage inverter converts the DC voltage and outputs an AC voltage to an AC power supply network. The DC link capacitor adjusts power outputted by the DC voltage/AC voltage converter to regulate the DC voltage.

摘要： The present invention discloses a control method for a soft switch circuit in a switch power source, which generates an alternating primary power filter current by controlling first and second primary power switching devices to be closed and opened, and generates an intermittent alternating resonant current in the same direction as the primary power filter current in a resonant branch by controlling forward and backward auxiliary switching devices to be closed and opened to thereby achieve closing of the first and second primary power switching devices at a zero voltage, and which generates a balance current with the same magnitude as and in the opposite direction to the resonant current in the resonant branch in at least a period of time during the resting of the resonant current by further controlling the forward and backward auxiliary switching devices to be closed and opened to thereby achieve an average current of zero across the resonant branch in a switching cycle. Without any additional balance circuit, this control method can address the imbalance problem of output power of the positive and negative direct current input voltage sources in a soft switch circuit of an existing switch power source.
