| Abstract |
Emerging wide bandgap devices are extending the operating frequency range and power handling capability of solid state based resonant power converter solutions. Presently, resonant power converters for industrial induction heating are using vacuum-tubes, achieving efficiencies of 50-65 \%. By replacing the prevalent vacuum tube technology with a solid state based solution, the efficiency of the industrial induction heating processes is expected to be increased. A design of a Class-E Push-Pull resonance converter using silicon carbide MOSFETs is proposed. A prototype, operating at 2.5 MHz, has been built showing a proof-of-concept of the topology at 4 kVA, achieving an efficiency of 91.8\% with a representative industrial induction heating load. |
