4.28 Bearing Pulse Width Modulator Amplifier
Figure 4-251 PWM
4.28.1 PWM Function
The PWM Amplifier supplies current to the radial and axial magnetic bearing coils as commanded by the BMCC. In
return, the PWM passes feedback from the current sensor for the bearing coils to the BMCC. Refer to Figure 4-252
Bearing Control Signal Flow on page 226.
The Backplane provides the PWM with +5VDC with respect to 0VDC, along with +17VDC and HV+ (at 250VDC) both
with respect to HV-.
