Patent JP-S63190389-A (JP)
Title: Power source signal generating circuit
Inventor: TOGAWA JIRO
IPC: H02H3/24
Filed: 1987-02-03
Abstract: PURPOSE:To obtain a signal synchronized with a power waveform in an extremely small power loss by a method wherein a diode is provided for preventing a first light emitting device from being applied with a reverse voltage. CONSTITUTION:A condenser 19 with adequate capacitance is used as a substitute for a resistor for preventing loss, and a clamping diode 16 is connected in parallel with a light emitting diode 14 in the reverse direction for preventing a reverse current from passing through the light emitting diode 14. Therefore, a current flowing the light emitting diode 14 is controlled by the effect of the condenser impedance and furthermore, the condenser itself incurs no power loss because its current phase is 90 deg. in advance of a voltage phase applied on its terminals. And, provided that an additional light emitting diode of a photo.coupler 10 is used as a clamping diode functioning in such a manner as to clamp the other terminal of the condenser on the other terminal voltage of a AC power source during a half cycle in which a light emitting diode is prevented from being applied with the reverse voltage and no current passes the light emitting diode, a synchronized signal might be obtained in every half cycle.
