BEHLKE HV Switches + High Voltage Pulsers in Silicon

DC-AC Power Electronics Converters for Battery Energy Storage

To ensure a highly efficient DC-AC conversion, the rated AC voltage should be kept as high as possible to reduce current stress in the semiconductors, which is the main cause of loss in the power electronics converter. A two-level (2L) VSC, a three-level T-type NPC converter, or an ANPC converter is the most widely used option.
