Two mode strong changes use the half bridge inverter in two operating modes to achieve efficiency in a wide power levels. By comparing with dual mode resonant converter the class D full bridge resonant inverter operates only in single mode where low range of power levels are not possible. The dual mode strong change can operate with Zero Voltage Switching and Zero Current Switching so the switching losses are minimised. Induction heating is the fast growing technology in domestic appliances it has high efficiency and faster heating times. In this paper dual mode deep change function has been used for heating system applications.
