Based on Qingzhengyuanhua’s technological achievements and experience in the ultra-high-speed drive field, this technology is downwardly applied to the home inverter refrigerator sector. The new refrigerator inverter drive has three core advantages: ultra-fast response, ultra-quiet energy efficiency, and long-term durability. It adopts an advanced parallel control algorithm architecture to achieve an ultra-high control frequency of 150kHz (5 times the industry mainstream). Combined with sine wave precision control technology, it reduces control current harmonics, enables faster compressor response, lowers operational pulsation, and reduces air conditioner operating noise.
