Abstract

PURPOSE:To exclude a means to obtain the effective value of a non-sinusoidal wave and a load voltage detecting means and accordingly to simplify the constitution of circuit, by carrying out the load phase control through the detection of the power supply voltage without detecting the load voltage. CONSTITUTION:A phase controlling switch means 13 like a triac, etc. is connected between a commercial AC power supply 11 and the load 12; and detecting means 14 and 15 detect the voltage value of the power supply 11. Furthermore a voltage-ignition phase converting means 16 decides the ignition phase of a switching means 13 in accordance with the output of the means 15. And an ignition pulse generating means 18 gives the ignition to the means 13 after generating an ignition pulse P with the ignition phse decided by the means 16. For instance, the means 18 supplies the voltage Vtheta corresponding to an ignition phase angle delivered from the means 16 and a pulse ZCP delivered from a zero cross detecting circuit 17 to produce the pulse P having a phase angle theta to the pulse ZCP.
