Mitsubishi Electric Corporation announced that it will begin shipping samples of its new 300A/1,200V and 300A/650V J1-Series power modules for electric and hybrid vehicles starting on October 31. The 300A/1,200V module is suited for high-voltage battery inverters used in hybrid buses and trucks. The 300A/650V module is designed for use in smaller-capacity inverters used in small EVs and mild hybrids.
These modules feature Mitsubishi's CSTBT (carrier-stored trench-gate bipolar transistor) IGBT technology that includes on-chip temperature sensing and on-chip current sensing for higher reliability and lower power losses. The forward voltage drops are 1.4V for the 300A/650V CT300CJ1A060 module and 1.7V for the 300A/1,200V CT300CJ1A120 module.
Mitsubishi is also offering potential customers an evaluation kit for these J1-series automotive power modules. The kit includes three elements: The Evaluation Printed Circuit Board with a custom gate-drive IC, optimized drive and protection circuits, drive signal isolations and a power supply. The DC-link capacitor assembly with two types of film capacitors optimized for use with the J1-series a board-mounted type with lower dc-line inductance and a block-type that features higher vibration withstand capability. And the kit includes a water cooling jacket to provide optimal thermal performance.
