The circuit of IGBT under diode clamped inductive load conditions is shown in Figure 1. This circuit is a commonly used IGBT circuit and can be used as a test circuit for IGBT switching characteristics to evaluate the on and off behavior of IGBT. Figure 2 shows the actual IGBT switch waveform obtained by comprehensively considering the recovery characteristics of diodes and stray inductance (Ls), which can be used as a reference for designing IGBT drive circuits. Firstly, we set the IGBT to operate under continuous steady-state current conditions, flowing through an inductive load and then through an ideal freewheeling diode parallel to the inductive load.

Singapore’s RF GaN chip vendor Gallium Semiconductor is closing its doors, including those of its R&D center in Nijmegen, The Netherlands. The decision to shut the company and let go of all the employees has been made by GaasLabs LLC, the investment company that wholly-owns Gallium Semiconductor and has funded it since it was founded in 2020. The decision was made following the death in November 2023 of John Ocampo, the founder of GaasLabs.
