UPS
Leveraging the full-chain synergy of its IDM model, crmicro provides customers with efficient and reliable device and module solutions, helping customers achieve uninterrupted power supply for critical equipment and stable system operation.
Solution Overview
Targeting the full range of UPS systems (off-line line-frequency, off-line high-frequency, and on-line), the solution covers the full chain: front-end power conversion, bidirectional inversion, multi-channel auxiliary power rails, isolated gate drive, and signal sampling. Integrating high-voltage SJ MOSFETs, low-voltage Trench/Planar MOSFETs, IGBTs, SiC devices, and full sets of driver & power management ICs, it delivers mains voltage regulation and uninterruptible transfer upon power failure, effectively improving overall conversion efficiency, load capability and long-term operating stability.
Solution Advantages
-
High-frequency double-conversion topology: pure sine wave output, clean and stable power
-
Optimized power devices reduce energy consumption, and improve equipment energy efficiency class
-
Multiple safety protection mechanisms provide surge and lightning protection for more reliable operation
-
Smart MCU control algorithm: millisecond switching response, zero equipment interruption
-
Fully self-developed technology ensures capacity and cost, supporting stable mass delivery
