Automotive A/C Compressor
Leveraging the full-chain synergy of its IDM model, crmicro provides high-reliability drive solutions for electric compressors, helping customers improve the energy efficiency and stability of automotive HVAC systems.
Solution Overview
Targeting the electronic control system for automotive A/C compressors, the solution covers the full chain: power inversion drive, auxiliary voltage regulation, and signal conditioning. Integrating IGBTs, SiC MOSFETs, SGT power MOSFETs, IPM power modules, precision op-amps and linear regulators, it enables stepless variable-frequency control of the compressor, optimizing overall energy consumption and operating stability under high/low temperature conditions.
Solution Advantages
-
Low switching loss, excellent conduction performance
-
Sensitive and precise variable-frequency regulation response
-
Lower operating noise and reduced heat generation
