A Novel Series of Intelligent Power Modules “V1 - MITSUBISHI ELECTRIC CORPORATION





V1-series is a new intelligent power module (IPM) which is mainly developed to increase
the efficiency of motor drives, power supplies like DC/DC converter. For this purpose
several new technologies have been implemented such as a new full gate CSTBT™ chip
and a newly developed dedicated control IC. The V1-series is a power module focussing
on applications in the two digit kW- class and, hence it has a line-up of 200A/300A/450A
in the 1200V class, and 400A/600A rating in 600V. Chip technology and structural
improvements reduce the effective junction temperature and increase the power and
thermal cycling capability of this family of IPMs while keeping widely terminal
compatibility with previous 2 in 1 V-series IPMs.

Executive Summary
The primary goal of this program was to develop a ballast system for plug-in CFLs (compact fluorescent
lamps) that will directly replace standard metal shell, medium base incandescent lampholders (such as
Levition # 6098) for use with portable lamp fixtures, such as floor, table and desk lamps. A secondary
goal was to identify a plug-in CFL that is optimized for use with this ballast. This Plug-in CFL Ballastin-
a- Socket system will allow fixture manufacturers to easily manufacture CFL-based high-efficacy
portable fixtures that provide residential and commercial consumers with attractive, cost-effective, and
energy-efficient fixtures for use wherever portable incandescent fixtures are used today. The advantages
of this proposed system over existing CFL solutions are that the fixtures can only be used with highefficacy
CFLs, and they will be more attractive and will have lower life-cycle costs than screw-in or
adapter-based CFL retrofit solutions. These features should greatly increase the penetration of CFL’s into the North American market.
