This high-power circuit was found in July 1986, Radio Electronics magazine, requiring a high-current source. Equivalent MOSFETs can be tested
In the figure we have a three-phase AC motor control for voltages up to 600 V or 1200 V depending on...
This circuit is more sensitive than the previous one, triggering when a laser beam that hits the...
We find this circuit in a 1980s Linear Technology documentation. The circuit can be implemented on the...
