PURPOSE:To control output voltage, etc., stably at high speed by performing closed-loop control of a mathematical model by using an arithmetic processing circuit, a pulse-width control circuit, a gate logic circuit and a model control function. CONSTITUTION:A mathematical model 8a and a model control function 8b are mounted to a control circuit section composed of an arithmetic processing circuit 6, a pulse-width control circuit 5, a gate logic circuit 4, etc. The model control function 8b performs closed-loop control of outputs Im, Vm from the mathematical model 8a. The model control function 8b prepares the manipulated variable Dm of the model 8a, and outputs it as a pulse-width command signal D. An output-voltage control function 8c prepares a command value Vr to the model control function 8b. Time delay by the processing time of a control arithmetic means and time delay by the response delay of a detector 7 can be avoided, thus stably controlling a controlled variable such as output voltage, output currents, output power or the like at high speed. |
