3.4 Compressor Control Overview

Refer to Figure 3-6 Compressor Control System Functional Block Diagram which shows a functional block diagram of

the compressor control and monitoring system. Refer to Figure 3-8 Magnetic Bearing Control System which displays

the component locations. The major components include:

Motor Drive

Soft-Start Board

BMCC

Bearing PWM Amplifier

Backplane

Serial Driver

HV DC-DC Converter

3.4.1 Motor Drive System

Normally, AC power to the compressor remains on even when the compressor is in the idle state. The compressor

motor requires a variable-frequency three-phase source for variable-speed operation. The AC line voltage is

converted into a DC voltage by SCRs. DC capacitors at the SCR output serve as energy storage and filter out the
