Mitsubishi Electric unveils 1200-V/50-A large-type dual in-line package intelligent power module
To save energy and elevate performance, a wide variety of current ratings ranging between several amperes and hundreds of amperes are rapidly being adopted for inverter-based motor drive systems.
DIPIPM, transfer molded intelligent power module are widely used in inverter-equipped appliances such as air conditioners, refrigerators and washing machines, as well as inverter motor drive systems for industrial applications. Mitsubishi Electric’s current 1,200 V, Large-Type DIPIPM Ver.4 series with a current rating of 5–35 amperes, help to minimize inverter system size.
The PS22A79 employs the newly developed sixth-generation IGBT (LPT-CSTBT: Light-Punch Trough Carrier Stored Trench-gate Bipolar Transistor), in which carrier storage is improved through cell pitch reduction and power loss is minimized through application of the thin wafer process. The model reduces power loss by 15% compared to the preceding fifth-generation IGBT.
Reduced power loss enables the current rating to be raised to 50 amperes, up from 35 amperes in the 1,200 V/35 A Large Type DIPIPM Ver.4 PS22A78 -E.
The model’s built-in temperature sensor offers improved linearity and precision compared with the existing PS22A78 -E model, resulting in more efficient heat control.
