Applications

The

general

hardware

architecture

of

the

reference design kit is based on an Inverter

topology suitable to efficiently drive three types of

motors: "3 phase BLDC/AC permanent magnet (in

six-step mode)" , "3 phase AC induction" and "3

phase BLAC PM motor (sinusoidal driven)" plus a

plug-in control board, based on ST7FMC MCU.

The

inverter

bridge

is

made

by

IGBT

SEMITOP3

®

module, including three phase IGBT

inverter. The driving of the bridge is made by three

IGBTs drivers (suited in the control board) with

high side/low side integrated functionality in a

single chip with also several protections. The

supply of the power is implemented using the

Viper, a Vertical Intelligent Power Enhanced

Regulators which combines an optimized, high

voltage, Vertical Power MOSFET with state-of-

the-art PWM circuitry.
