Abstract: The paper proposes an easy extraction path of almost static and dynamic parameters of a power MOSFET based on a laboratory technique that requires only one test circuit. Hard switching the power MOSFET on a resistive load, the gate charge, the forward transconductance, the on-state resistance and the switching times, and the intrinsic capacitances are extracted from the waveforms of the gate voltage, drain voltage, and drain current. The extraction procedure for all these parameters of device is described step by step in the paper. A simple test allows students to evaluate the switching performance of a power MOSFET and to teach the difference between MOSFET technologies comparing the Figure of Merit (FOM) index of devices. This test can be repeated for many MOSFETs and IGBTs to compare their overall switching performance and to observe the device behavior for various operating conditions of the device under test (resistive or inductive loads and different supply v!
oltages, and drive gate currents) and it can be used as an education tool in Power Electronics at its basic level.
