New standardised medium voltage package – the SEMITRANS20 overcomes the limits of conventional medium voltage module concepts and provides a new design approach for inverters in applications such as transportation, industrial drives and grid infrastructure. Optimised for the medium voltage market with the latest 3.3kV IGBTs, the SEMITRANS20 is designed as a half bridge configuration featuring a build-in temperature sensor and opposite DC and AC power terminals. Compared to conventional modules, the stray inductance is reduced by up to 75%, thus providing higher operational safety and easy paralleling. The new SEMITRANS20 allows a higher degree of scalability and flexibility in medium voltage inverter design. The standardised package meets the increasing demands for lower cost, higher efficiency and durability for power electronics in industry, transportation and infrastructure.
