The induction heating appliances of thyristor have been widely used in industrial cooking. An approximate analysis of medium frequency parallel converter used in power supply controlled by microcomputer is presented in this work. The proposed approach may be applied to converters whose industrial applications are induction heating and metal melting installations. It is shown that closed loop circuit feedback control and opened loop circuit control are separated during the zero-power start-up process. The self-starting of the medium frequency parallel converter is achieved. A practical design in hardware and software of the control system is also obtained. The experiment results on power system proved the flexibility and reliability of the digital system. |
