Key Considerations for Enhancing the Partial Discharge Capability of High Voltage Power Semiconductor Modules

The escalating demand for high-voltage (HV) power semiconductor modules, which are crucial for enhancing system efficiency and supporting higher operational frequencies and temperatures, necessitates significant attention to optimizing both performance and reliability. HV modules often require paralleling multiple chips to meet current ratings, making it essential to ensure balanced power loop inductance paths to prevent current imbalances and potential system failures. As the industry advances towards HV modules operating at 15-20 kV, achieving robust partial discharge (PD) performance is vital for maintaining system integrity.
