Parallel connected power devices such as Insulated Gate Bipolar Transistors (IGBTs) can be used to realize a system with higher current and higher power rating. However, the operation of parallel connected IGBTs is prone to unbalancing due to variation in parameters of the semiconductor devices and asymmetric parallel system. In this paper, feedback control is proposed for peak overshoot minimization as well as current balancing of parallel connected IGBTs. A fully digital feedback control (DFC) is implemented using the universal clock for balanced operation of the two parallel connected IGBTs.
