A medium-voltage motor drive typically has a voltage between 3kV and 10kV. It adopts half-bridge cascaded connection or high-voltage power semiconductor devices in multi-level topologies. The power is in megawatt level. Bronze Technologies can provide mature and high-quality solutions for customers with high-voltage drive and multi-level drive requirements.
