LOAD CONTROL DEVICE AND LOAD CONTROL METHOD

Title:

LOAD CONTROL DEVICE AND LOAD CONTROL METHOD

Document Type and Number:

Japanese Patent JP2019041198

Kind Code:

A

Abstract:

To provide a load control device and a load control method that can suppress abnormal heat generation and resistance deterioration.SOLUTION: Semiconductor relays CH11, CH14, CH21, and CH24 are connected in series to the same load 21 and connected in parallel with each other. Semiconductor relays CH12, CH13, and CH22 are connected in series to the same load 22 and connected in parallel with each other. When a control unit 14 detects an abnormality in the semiconductor relays CH11, CH14, CH21, and CH24, the control unit turns off all the semiconductor relays CH11, CH14, CH21, and CH24. In addition, when the control unit 14 detects an abnormality in the semiconductor relays CH12, CH13, and CH22, the control unit turns off all the semiconductor relays CH12, CH13, and CH22.SELECTED DRAWING: Figure 1
