1 Introduction
Introduction of the reference board
1.1 Overview
The Inverter Reference Board with Fujitsu’s FM3 family is intended to aid the user in the
rapid evaluation and development of motor control applications using MB9B500 Series MCU
which are embedded with ARM Cotex-M3 CPU core. This reference board is targeted to
control Permanent Magnet Synchronous Motors in sensor-less operation.
The reference board has a three-phase power module device that contains the motor
inverter and the gate driver’s circuit. It also has Power Factor Correction (PFC) circuitry and
in order to provide a full set of tools used in motor control applications. If the user doesn’t
need PFC stage, a rectifier module is also provided for selection. Figure1-1 is a system
block diagram of Inverter Reference Board.
The rated continuous output current from the inverter is 10A (RMS). This allow up to 2.2KW
output when running from a 220V single-phase input voltage in a maximum 25ºC ambient
temperature environment.

Getting start with the hardware, firmware and software
2.1 System Components
This reference system is made up with three daughter board. They are:
Power Board
This board contains the EMI filter stage and an AC-to-DC module. The AC-to-DC
module can output a stabled 15V (15W) power line. It will be transformed to two 5V
power lines through line regulators, one is for MCU system and another is for
cooling fans. At the same time, isolated 5V power line comes from the 15V line by
isolated DC-to-DC, and another isolated 5V is for isolation communication device.
AN706-00042-1v0-E
Inverter Board
There are PFC stage and Inverter stage, as well as a full bridge rectifier module
provided for selection when the user doesn’t need PFC stage.
DC-Link Board
DC-Link Board can make smoothly 100Hz half-sine-wave power and it can provide
to DC bus through three electrolytic capacitors.
The input and output cables should be with the minimum current rating of 10A.
Figure2-1 shows the connection of the boards.
