Electrical Control System

摘要

There is provided a semiconductor device including a power compensation circuit in an apparatus in order to notify of a power supply disconnection failure that a user of the apparatus may not recognize. The power compensation circuit includes a rectifier circuit and a detection circuit. The rectifier circuit is coupled between a first power supply line and a second power supply line. If the voltage of the second power supply line is lower than the voltage of the first power supply line by a predetermined value or more, the rectifier circuit supplies power from the first power supply line to the second power supply line. The detection circuit outputs a detection signal when the current flows through the rectifier circuit.

1. An electrical control system comprising:
a drive system block that receives power supply from a main power supply through a first power supply route to drive a load; a control system block that receives power supply from the main power supply through a second power supply route to control the drive system block; a power compensation circuit provided between a first power supply line within the drive system block and a second power supply line within the control system block, the first and second power supply lines being coupled to the first and second power supply routes, respectively; and a notification device for notifying abnormality, in response to a signal based on a detection signal output from the power compensation circuit, wherein the power compensation circuit includes: a rectifier circuit coupled between the first and second power supply lines, to supply power from the first power supply line to the second power supply line when the voltage of the second power supply line is lower than the voltage of the first power supply line by a predetermined value or more; and a detection circuit for outputting a detection signal when a current flows through the rectifier circuit.
