How to measure MOSFET drain voltage and currentChris Lee
Two pulsed I-V channels are typically used to measure these MOSFET I-V curves with one channel connected to the gate and the other to the drain. The ground of each channel is connected to the MOSFET source pin. To construct the transistor curves, the gate channel first applies voltage to ...
Also, when checking the waveform, what kind of waveform should I measure before determining the above two factors?Do you understand that the voltage and current short-circuit time are checked from the short-circuit test circuit to confirm that they do not exceed the rating of the SW...
Here's an automotive control board I'm making, it'll have a bunch of inputs and drive 3 FETS along the top right (something like an IRF540 or better), I'm thinking of a switching frequency around 2-5khz. They're supposed to handle a peak load of about 10-15A, but that will be...
The analysis is focused on the charging and discharging of a transistor gate, and on the impact that such operation has on EMI. The ST L9945, an 8-channel configurable HS/LS pre-driver, is considered as the reference device to be used in several applications (P&H, H-Bridge,...
Motor response time is closely related to torque, with high-torque motors typically having faster response times. An easy way to measure response time is to assess how long it takes for a motor to reach maximum RPM from 0. Response time is heavily influenced by the weight and pitch of your...
