Application note
PFC for ST7MC starter kit
Introduction
The aim of this Application Note is to give an example of how to use the ST7MC microcontroller to
implement the Power Factor Correction (PFC) inside a motor control application. The ST7MC
microcontroller is provided with a Motor Control Peripheral which has been developed to implement motor
control function for Induction motors and Permanent Magnet Synchronous motors. The motor control
peripheral leaves the microcontroller resources free to perform the power factor correction.
The power factor correction technique utilized is called “transition mode”. The hardware used to realize
the system is the ST7MC Starter Kit plus an additional external power board called “Add On”.
In this application note, theoretical information about the PFC control method is given, in addition to an
explanation of the software routine able to manage the PFC stage and the calculation of the Add On
components.
The reader can find extra information about the motor control related routines the application note
AN1904.
