Description
IRMCS3012 is a reference design platform for IRMCF312, a high performance RAM-based motion control IC designed
primarily for appliance applications, up to 1.5kW 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 two inverter
stages, all of which are controlled by the IRMCF312 digital IC
simultaneously. The power stage c
ontains a Trench IGBT
(IRGB4063PbF) for the PFC and an integrated power module (IRAMX16UP60A-2) for the first inverter, and another
integrated power module (IRAM336-025SB) for the second 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.
