  • Energy conservation is one method from the government to improve the use of energy in Indonesia. High frequency inverter design which is used as an induction heating device appropriate conservation measures. This design is chosen because it can be applied to any process that requires heating by using a material with high conductivity. In this study, the heater is used to liquefy lignite. Induction heating requires high-frequency inverter module. Using the AC voltage single phase rectified to a bridge rectifier, inverter will convert AC voltage into DC voltage, 12V – 22V, which electrical quantities with a frequency can be set. Voltage is derived using a step-down transformer that is used little power. Once out of the step-down transformer is passed a winding inducer which induce object to be heated. The measurement results show inverter module that is made has a frequency of 40 kHz and can generate heat the sample up to 401 degrees Celsius within 5 minutes with the inverter efficiency of 82.8%.
