Our "DC Inverter Air Conditioner Compressor Driver" features an integrated interleaved PFC (Power Factor Correction) function and utilizes sensorless position/current vector control inverter technology, making it a highly efficient and cost-effective driver for brushless DC motors (BLDC). All control is implemented with a single-chip microcontroller. For high-end applications, the same microcontroller can also control fan motors via inverter. Additionally, we accept contract development for consumer (white goods) applications. Please feel free to contact us. 【Features】 ■ Brushless DC motor driver ■ Sensorless position/current ■ Vibration suppression function for single rotary applications ■ 180-degree conduction (sine wave drive) ■ Interleaved PFC (Power Factor Correction) function *For more details, please download the PDF or feel free to contact us.
