New power module has power loss reduction and lower noise

13 July 2005 Power Electronics / Power Management

In addition to needs for high performance, compactness, and power-loss reduction in motor-control devices for industrial equipment such as general-purpose inverters and AC servos, recent years have seen regular increases in the requirements for ease-of-use and environmentally-friendly equipment.

Mitsubishi Electric had already released the S-DASH Series IPM (intelligent power module) product in response to the demand for these types of modules, and in this latest development the company has produced its latest IPM product, the fifth-generation L Series IPM. This achieves both power-loss reduction by adopting CSTBT chips in the IPMs and smaller and lighter equipment through the use of a new form of package. CSTBT stands for 'carrier-stored trench-gate bipolar transistor,' which is a transistor with an additional carrier-stored layer in the trench gate to improve the trade-off performance between Eoff and VCE(sat) .

The new L-Series IPM's key features are: low saturation voltage; the new integration enables a reduction in EMI and a major reduction in the current consumption in controlled power supplies; new compact package; increased rated current in the brake parts.

The L-Series is optimised for applications such as miniaturising inverters in power-source equipment such as UPS units, and for motor-control equipment such as inverter servos for 220 V and 440 V a.c. equipment. It is also applicable to solar-power and wind-power equipment.
