AEMEnergy has launched the world’s first quasi-resonant soft-switching SiC modular PCS, enabling multi-unit operation. Using proprietary technology, it achieves soft switching with zero-current turn-on and zero-voltage turn-off for power switches, and zero-current/voltage turn-off for diodes. This greatly reduces switching losses, breaks through frequency limits of high-power PCS, and boosts power density and efficiency across the full power range.
Integrated Design
Combines EMS, BMS, and PCS functionalities
Multi-Unit Operation
Virtual synchronous control enables parallel operation of multiple voltage sources
Unbalanced Load Support
Handles 100% unbalanced loads
SiC Soft-Switching Technology
Uses silicon carbide devices for high conversion efficiency; modular design allows easy installation and maintenance
