| Abstract: | Inverters for induction heating have been applied in surface-heat-processing of metal parts and metal melt- ing.For the small parts surface-heat-processing, both the frequency and power of the inverter should be high enough.An in- verter consist of high-speed MOSFETS is introduced.The frequency and power are IMHz/5kW respectively.A high-speed PLL MM74HC4046 is used for power control.The experimental results improve the design. |
