ABSTRACT:
A three-phase bridge inverter for controlling a motor with a variable speed includes a drive circuit therefor and an overcurrent protection circuit on one integrated chip. The inverter IC can be operated by directly inputting a direct current obtained by rectifying commercial 100 V. Thus, the inverter chip reduces the size and the weight of a system, improves the usability, lowers the cost thereof and permits mass production fabrication. Also, the life of the IC is increased by detecting current flowing through the inverter and the temperature of the chip and stopping the operation, when an abnormality is found.
