Abstract
Along with the maturity of power electronic technology continuously, induction heating technology with its many advantages has been widely used and developed rapidly. However, due to the disadvantages of series resonant induction heating power, such as low input power factor, great grid pollution, it will bring many hazards. This article will make induction heating power network-side input power factor approximate unit power factor with using Active power factor correction technique, and it makes the net side current and voltage be same phase standard sine wave , reduces the network pollution; and with using DC chopper circuit to complete the adjustment of DC voltage, it achieves induction heating power changes. At the same time, using Matlab software for modeling and simulation analysis on the main circuit and control circuit, the simulation results comply with the design requirements and verify the feasibility of the system design.
