The Pace-Setting Performance and Features of the 56F8300 Hybrid Controllers

Figure 1-10. PWM Fault Decode And Automatic Clearing

Figure 1-11 demonstrates how the two PWM modules present on many of the 56F8300 components

can be used. In this example, it performs unity power factor correction (power flow direction control)

with regeneration to mains. The second PWM could also be used to drive an independent three-phase

motor.
