invokes function from the Milestone Callback Table, which performs calculation and correction of
PFC reference value or activates inhibit output. This procedure allows easy modification of the
sequence of events.
PFC control operates from event handlers and excludes peripheral initialization and DCBus voltage
measurement. The PFC control is developed to easily incorporate motor control applications. The
Main routine calls to the PFC initialization function and passes the value of the DCBus voltage to PFC
control, allowing measurement of DCBus voltage with different sample rates and ADC modes. This
application demonstrates initialization and use of PFC control.
The Main routine provides:
•
•
•
•
•
•
Initialization of the Analog-to-Digital Converter
Initialization of the Timer
Initialization of the Switch and LEDs
Initialization of Brake control
Initialization of the PFC routine call
