Overview
This reference design is based on 32-bit DSC MC56F84789, to demo a 3in1 Air-Conditioner Outdoor Unit. This reference design jump-starts your ability to leverage the NXP® DSCs' advanced feature sets via complete software, tools and hardware platform.
- High performance, low cost all DC VF air-conditioner outdoor unit control system
- Three control objectives (interleaved single-phase PFC converter, fan and compressor) with one MCU device
- Input voltage range of 85 – 265VAC/40 – 70H
- Single-phase two channels interleaved PFC converter compatible with global mains input, 99.9% power factor, 8% input current THDi
- Sensorless FOC algorithm for both compressor and fan
- Anti-typhoon startup for fan, and on-line load torque compensation control for compressor to reduce system vibration and noise
- Reliable startup performance under full load and input voltage range
- Extreme low/high speed (from 1Hz to 150Hz) performance with extended flux observer
- Over-/under-voltage, over-current, over-temperature, over-input power protection and lock of rotor detection
- FreeMASTER GUI for easy debugging
