Title: A DETAILED STUDY OF THE HIGH ORDER SERIAL RESONANT INVERTER FOR INDUCTION HEATING Keywords: serial inverter, resonant inverter, high-order circuit, charAbstract: The real high order power circuit of the serial resonant inverter without free- wheeling
diodes widely applied for induction heating and melting is analyzed assuming a sine-wave
shape of the load voltage. The load circuit is replaced by serially connected equivalent
resistance and reactance. The parameters of the inverter circuit, especially the load voltage,
the voltage across the power semiconductor devices and in the thyristor variant the circuit
turn-off time are determined. A MATLAB program calculates and graphically displays the
frequency controlling characteristics. A direct ste References - Popov, E., 1978, Automatic Control of Serial Thyristor Inverters with Varying Load, Ph.D., <VMEI-Sofia>
