Electric compressor controller

An efficient electric compressor controller based on self-developed SiC or ultra-fast IGBT modules, achieving a peak efficiency of up to 99%. It supports ultra-low temperature heat pumps and multiple refrigerants including R290, R407C, and R134A, as well as triangular cycle operation. The operating temperature range spans from -40°C to 125°C, covering voltage platform requirements from 160V to 1000V, and is compatible with electric compressors with displacements ranging from 27CC to 56CC.
