| Abstract |
To ensure reliable and trouble-free parallel operation, the parameters which affect the
transient behaviour of the semiconductors must be analysed. In this paper, the influence of the stray
inductances on the waveforms during commutation is studied. For this purpose, the PEEC method is
employed for inductance calculation. Conditions allowing an equilibrium current sharing and equal
over-voltages on the paralleled devices are obtained. Based on developed conditions, a structure
involving two paralleled power MOSFET modules is proposed. Simulation and experimental results
are given to validate the proposed approach. |
