Application note
Digital PFC and dual FOC MC integration
Introduction
This application note explains how to integrate two sets of firmware to manage a digital PFC
and a dual field-oriented control (FOC) motor control driver by means of a high-density
STM32.
The purpose is to evaluate the potentiality of an STM32 to control a high-power PFC with
performances comparable to a standard continuous mode PFC monolithic IC, while allotting
sufficient micro resources (such as program memory and CPU computational capabilities)
to make other complex operations such as the simultaneous driving of two 3-phase, field-
oriented control motors in sensorless and single-shunt mode.
Section 2 and Section 3 briefly describe the implementation of a digital PFC and dual motor
control FOC with an STM32, while Section 4 describes how to integrate these two parts in a
single firmware with the main focus on the use of the STM32 resources and constraints.
