Abstract-
In this paper, a new complementary gate driver for power metal-oxide semiconductor field-effect transistors and in sulated gate bipolar transistors is presented based on the use of a piezoelectric transformer (PT). This type of transformer has a high integration capability. Its design is based on a multilayer struc ture working in the second thickness resonance mode. A new de sign method has been used based on an analytical Mason model in order to optimize the efficiency, the available power at the trans former secon ....etc

Active Gate Control for Current Balancing of
Parallel-Connected IGBT Modules
in Solid-State Modulators

Dominik Bortis, Student Member, IEEE, Juergen Biela, Member, IEEE, and Johann W. Kolar, Senior Member, IEEE


Abstract—

In modern pulsed power systems, often, fast solidstate
switches likeMOSFETs and insulated gate bipolar transistor
(IGBT) modules are used to generate short high power pulses. In
order to increase the pulsed power, solid-state switches have to be
connected in series or in par ....etc

Abstract
High Voltage IGBT (HVIGBT) modules with high performance in the areas of low power loss and high reliability are required for high power applications such as traction, large industrial motor drives, and medium voltage converters. Unfortunately, these performances are often in reciprocal relationship. In order to achieve a higher performance with optimized tradeoffs at the 3.3kV level, a new IGBT and Free wheeling Diode (FWD) chip set was developed. This paper describes the optimization of the chip design ....etc
