This paper aims to present a modified half-bridge inverter for applying as a dual-output induction heating machine. By using a series-resonant principle, the output power of inverter could be adjusted. In addition, main switches in the circuit could operate under a zero-voltage switching condition (ZVS) resulting in eliminating switching power losses during the turning on stage. The proposed circuit was designed, built and tested at 1,300 W of total rated power (650 W for each load), 230 V 50 Hz of AC input voltage and 40 - 50 kHz of switching frequency by using three sizes of iron work pieces (12, 9 and 6 mm of diameter). From experimental results, the maximum efficiency of inverter was 98.67 %.
