摘要： An inverter power supply system includes a half-bridge inverter circuit which includes a first switching element, a second switching element, a first auxiliary capacitor and a second auxiliary capacitor for converting a DC voltage from a DC power supply circuit to an AC voltage. An output control circuit outputs a first output control signal and a second output control signal with a phase difference of a half cycle to control the inverter circuit. An inverter driving circuit turns on the first (or second) switching element when the first (or second) output control signal turns ON while turning off the first (or second) switching element upon lapse of a first (or second) delay time for allowing the first (or second) auxiliary capacitor to discharge to a predetermined level after the first (or second) output control signal turns OFF.

摘要： A power supply for performing arc-machining operation includes a primary rectifier connected to the commercial AC power source and an inverter coupled to the rectifier. A switching device is provided between the rectifier and the inverter. By controlling the power supplied from the rectifier to the inverter, the switching device prevents a large switching loss from occurring in the inverter.

摘要： A power supply for arc welding includes switching elements PTR, NTR for switching the polarity of the direct voltage from a power circuit PMC. The element PTR is connected in parallel to a series unit of a switching element TR1 and a resistor R1. Likewise, the element NTR is connected in parallel to a series unit of a switching element R2 and a resistor R2. A necking determination circuit ND determines whether a constriction occurs at the molten bridging portion between the welding wire and the base material. When the constriction occurs during the “electrode positive” mode, the switching element PTR is turned off, while the switching element TR1 is brought into the conduction state. When the constriction occurs during the “electrode negative” mode, the switching element NTR is turned off, while the switching element TR2 is brought into the conduction state.
