Title:
POWER SUPPLY VOLTAGE GENERATING UNIT FOR MARINE POWER SUPPLY
Document Type and Number:
Japanese Patent JPS5925599
Kind Code:
A
Abstract:
PURPOSE:To prevent an erronous operation of the titled unit by a method wherein, when the output voltage from a generator exceeds a specified allowance, a normal conversion control unit and a reverse conversion control unit are operated. CONSTITUTION:A power supply voltage generating unit 11 is supplied with the output voltage from a generator 1 through the intermediary of a transformer 9 and a rectifier 10. When the output voltage from the generator 1 exceeds the reference level in said generating unit 11, the output from an amplifier 20 attains to higher level turning one transistor 25 ON and the other transistor 28 ON through the intermediary of one photocoupler 27 and another transistor 30 ON through the intermediary of the other photocoupler 29. A normal conversion controller 7 and a reverse conversion controller are supplied with the constant voltage generated by a constant voltage circuit 12. Through these procedures, a load may be supplied with the output voltage from the generator 1 through the intermediary of a normal conversion circuit 3 and a reverse conversion circuit 4.
