Abstract
PURPOSE:To prevent a small-sized and lightweight welding transformer from being damaged by detecting the magnetic saturation based on the variation of a primary current of the welding transformer to control a switching action of an inverter according to a detected signal. CONSTITUTION:In order to detect the magnetic saturation of the welding transformer 20, a current sensor 38 is provided to wiring between a primary coil of the welding transformer 20 and an output terminal of an inverter circuit 18. Then, an output signal of said current sensor 38 is supplied to a primary current detection circuit 40 which supplies an output signal SI corresponding to the primary current Ip to a magnetic saturation detection circuit 42. The magnetic saturation detection circuit 42 produces a detected signal MS indicating a magnetic saturated state of the welding transformer 20 and in response to said signal MS, a pulse width control circuit 32 controls the switching action of the inverter circuit 18 so as to regulate the pulse width of the primary current Ip when the magnetic saturation is generated.
