PROBLEM TO BE SOLVED: To provide an inverter circuit, capable of operating various loads in an optimum state. SOLUTION: A DC/DC booster section 2 determines the output voltage in accordance with the pulse signal created by a control section 12 at the primary side. A switch 11 is used for selecting the kind of load by an user to be connected for the inverter circuit. The control section 12 at the primary side determines the duty of a pulse signal for controlling the DC/DC booster section 2. An H-bridge circuit 6 converts the DC voltage into an AC, in accordance with the control of the control section at the secondary side and controls the H-bridge circuit 6 in such a manner that the output of the H bridge circuit 6 becomes AC which has an effective value of 100 Vrms. |
