ABSTRACT:
A power supply board for connecting dry communication lines from a remote station to the electronic equipment at a power station and includes a brushless PM motor mounted in a motor section of the board. The motor is powered by a station-derived low voltage direct current source provided at the power station. A brushless PM generator is mounted in a spaced alternator section on the board. The motor and generator shafts are connected by a flexible tube for generating a voltage suitable for operating of the electronic equipment at the power station. An integrated motor drive circuit is mounted on the motor section and connected to the D.C. source via a protective circuit. The motor has a bank of Hall cell sensors for generating position control signals to the circuit for sequential energization of the three phase motor winding. The output of the alternator is rectified to establish an output voltage for operating the communication equipment. A voltage sampling circuit is coupled to the rectified output and connected by electrical/optical isolators and a fiber optic feedback line to the integrated circuit to create a closed loop system establishing a constant output voltage for operating the equipment.
