Title:
電子スイッチ装置
Document Type and Number:
Japanese Patent JP7026320
Kind Code:
B2
Abstract:
The present disclosure addresses the problem of making it possible to adapt to a greater number of types of loads. An electronic switch device 1 is provided with a main switch unit Q1, an auxiliary switch unit Q2, a detection unit 3, and a control unit 5. The main switch unit Q1 switches between energy conduction and non-conduction between an alternating current power source 11 and a load 12. The auxiliary switch unit Q2 switches between supplying and not supplying a drive power that is supplied in order to drive the main switch unit Q1 from the alternating current power source 11. The detection unit 3 detects a zero cross of an inter-switch voltage Vsw, which is the voltage between both ends of the main switch unit Q1. The control unit 5 controls the auxiliary switch unit Q2. The control unit 5 controls the auxiliary switch unit Q2 so that the drive power is supplied to the main switch unit Q1 for a predetermined period of time if the zero cross of the inter-switch voltage Vsw is detected at the detection unit 3.
