IGBT H-Bridge Inverter

Andy made valid points, however, I respectfully disagree. Firstly, when the secondary of the transformer is OC (open circuit), the transformer would behave like a simple inductor. When a positive ...

How do I test a MOSFET/IGBT for its maximum current and maximum voltage mentioned in the datasheet practically?

The way this is done in industry (that is, to take data needed to write the datasheet) is by using either a curve tracer like a Tektronix 370A, a semiconductor parameter analyzer like the Agilent/...

How do I test a MOSFET/IGBT for its maximum current and maximum voltage mentioned in the datasheet practically?

You can measure VCES by applying the specified current. Typically through a large-value resistor from a high voltage supply, to avoid potential capacitive discharge events that will likely destroy ...

I would call that device an adjustable power supply with current limit capabilities. For pulse testing, you can get by with a capacitor bank and a much smaller power supply.

120VAC to 90VDC Power Supply (for DC Stepper Motors)

Just used 2 48v 20A supplies adjusted to 45v connected in series to get 90v to power a treadmill 2.5hp brushed motor through a PWM controller to power an Atlas 10-54 lathe. Works like a charm. ...
