描述
Renesas' Air Conditioner Outdoor Unit (ODU) reference design is a total solution for controlling outdoor air conditioning units. It is used in combination with the MCI-HV-AC which is AC200V high-voltage inverter board, communication board, and peripheral devices. It is capable of evaluating and developing dual motor control with the provided permanent magnet (PM) sensorless vector control sample code.
特性
- Reference design integrating the RX26T microcontroller and a 3-phase inverter circuit
- Dual motor control function (compressor and fan)
- Open-loop start (current pull-in control) during stop and low-speed operation
- PM sensorless vector control using induced voltage observer during medium to high-speed operation (1-shunt and 3-shunt)
- Flux weakening control for high-speed operation and maximum torque per ampere (MTPA) control for IPMSM
- Torque vibration suppression function, step-out detection, and flying start (catching control)
- Single-phase and interleaved PFC control (power factor correction and boost function)
- MCI-HV-AC inverter board features
- Supports single-phase AC input (AC100V ~ 240V, 50Hz/60Hz)
- Supports 2-motor (compressor, fan) control
- Equipped with overcurrent detection, overvoltage protection, and overheat detection functions
- Equipped with a four-way valve and expansion valve control interface
- Equipped with temperature control sensor interface
- Equipped with air conditioner indoor unit communication interface

| 应用说明 | Dual Motor Control with Interleaved PFC for Air Conditioner Outdoor Unit Reference Design
AI 生成的摘要:
The document details dual motor control algorithms combined with interleaved power factor correction (PFC) for air conditioner outdoor units using Renesas RX26T MCUs. It covers sensorless vector control for permanent magnet motors, including open-loop startup, BEMF observer-based control, flux weakening, and maximum torque per ampere (MTPA) control. The design integrates two 3-phase inverters for compressor and fan motors, with advanced features like torque vibration suppression, stall detection, and flying start. It also explains hardware setup, software configuration, motor operation, and PFC control algorithms, providing comprehensive guidance for inverter development and evaluation.
