描述
Modern washing machines often struggle to deliver high energy efficiency and quiet operation while maintaining long-term reliability under real-world conditions. Inefficiencies in power conversion and vibration during motor operation can increase energy consumption, acoustic noise, and stress on system components.
This system demonstrates an integrated washer-dryer architecture built around coordinated power factor correction (PFC) and multi-motor brushless DC (BLDC) control across washing and drying functions. A GaN FET-based PFC stage improves power conversion efficiency and supports stable operation under varying loads, while MCU-based system coordination manages the BLDC drum, dryer fan, and heat pump motors, enabling efficient and quiet operation. Built-in wireless connectivity enables IoT functionality for monitoring and control.
System Benefits:
- High-efficiency motor drive with precise control reduces energy consumption across washing and drying cycles.
- Quiet operation enabled by BLDC motor control minimizes vibration and noise.
- Electrical isolation using isolation amplifiers and photocouplers enhances safety and reliability.
- Flexible Renesas MCU lineup supports scalable performance and feature expansion.
- Built-in Wi-Fi® and Bluetooth® Low Energy (LE) support IoT-enabled monitoring and control.
