PURPOSE:To stabilize the output and to realize highly accurate initial setting of output by a constitution wherein one of two switching elements, connected in series across a DC power supply, is self-excited while the other is externally excited and fluctuation of ON interval of self-excitation is suppressed through control of ON interval of external excitation. CONSTITUTION:The inverter unit comprising an externally excited switching element Q2 having ON interval determined through control of charging and discharging current of a capacitor C1 is additionally provided with a regulating means 21 for controlling the charging and discharging currents in opposite directions while interlocking. |
