Abstract

Abstract:

Because of the limitation of a single IGBT’s rating voltage, series connect of IGBTs can solve the problems working in high voltage-high power applications. IGBTs in series connection not only have higher voltage rating, but the switching performance is also the best under the same voltage level. The voltage imbalance caused by local overvoltage is the most important problem of the IGBTs series, it needs to adopt a suitable control method to solve the problem. This paper discuss the operating principle and characteristics of two voltage balancing methods, one is the active clamp control the other is the gate-balancing core control. By comparing the advantage and disadvantage of two methods. A hybrid control method combining two methods is proposed to make up for the shortage of both methods .The reliability and stability of hybrid mothed is verified by the simulations in the PSPICE software.

Key words: IGBT series connection, voltage-balancing, active clamp control, gate-balancing core control, hybrid control
