Description
IRMCS3043 is a reference design platform for IRMCF343, a high performance RAM-based motion control IC designed
primarily for appliance applications, up to 1.7kW continuous input power. It’s mainly aimed to achieve simple, low cost and
high performance solutions for advanced appliance motor control. It consists of an active PFC frond-end and an inverter
stage, both of which are controlled by the IRMCF343 digital IC simultaneously. The power stage contains a Trench IGBT
(IRGP4063DPbF) for the PFC and an integrated power module (IRAMX16UP60A-2) for the inverter, which are part of
iMOTION^TM chipset. Users can readily evaluate high performance sensorless control with MCEDesigner^TM software without
spending development effort usually required in the traditional DSP or microcontroller based system. The complete B/Ms,
schematics and layout are provided so that the user can adapt and tailor the design per application needs.
