Filed: 1988-12-13
Abstract: PURPOSE:To prevent spark discharge from being produced at a contact, by producing opening signals by which opening of a switch is delayed by a preset time in addition to the time from the zero point of the output of a load current waveform detector after opening operation to the zero point of a load current. CONSTITUTION:When a switch 2 is closed, an input source voltage 7 is applied from an ac supply 1, and a load current 8 is caused to flow through a load 5. When opening operation 6 is performed for a controller 4 at time t, the controller 4 detects the moment t at which a detected waveform 9 sent out from a load current waveform detector 3 becomes 0 for the first time after the time t, and produces an opening signal 10 after a preset delaytime DELTAt in addition to the t0. The opening signal 10 is inputted to the switch 2 to make it possible to break the circuit at the moment that the load current is 0. It is thus enabled to prevent spark discharge from being generated at the contact of the power switch so that increase of contact resistance and/or shortening of the life of the switch become hard to occur.
