Abstract :
This paper presents a 4 kW 400 kHz voltage source inverter for induction heating applications, which is characterized by power control based on PDM (pulse density modulation). The pulse density modulated inverter makes an induction heating system simple and compact, thus leading to higher efficiency. The modulation strategy is proposed to realize an induction heating system capable of operation at the frequency and power level of interest. Some experimental results are shown to verify the validity of the concept.<>
