IMPORTANT NOTICE: This video fixes a problem with the Scope Probe in the last mosfet video that caused an inaccurate display of the Drain Trace waveform. The previous video concerning the effect of Offset…
Here I continue to demonstrate the versatility of the simple Arduino pot-voltmeter system. NOTE: I get scrambled when I describe the mosfet pin hookup. The Load has no connection to the mosfet gate, it…
A simple circuit describing high-side switching using a random N-channel mosfet. Also showing that the gate needs only Charge to switch and if the Charge stays on the gate it keeps the mosfet ON….
This video illustrates the effect of Function Generator Offset setting applied to the Gate on the behaviour of an IRFPG50 power MOSFET. IMPORTANT NOTICE: The scope probe waveform trace shown in this video is…
ERRATUM: A couple of times I say “Drain” when I should have said “Source”. The actual intent is clear, I hope, since the wires are color coded. This video refutes the assertion by Rosemary…
Here I show the simple DC Gate Threshold Voltage test for the IRFPG50 n-channel MOSFET. It is pretty easy to see that a voltage fluctuating around 4 volts on the gate is sufficient to…
The IRFPG50 is one tough transistor. Erratum: The duty cycle changed when I changed the range setting on the FG, and did not preserve the approx. 20 percent I had dialed in. Instead the…
When an N channel mosfet is configured to switch a high side low impedance load, the Drain voltage is HIGH when the mosfet is OFF, and when the mosfet is ON, the drain voltage…
Usually we think of turning on a MOSFET by raising its Gate voltage to 10 or 12 volts above the negative rail/source voltage. But what if the Gate is pinned to circuit ground or…
This is my new RODIN Z44N MOTOR, that consist in a new circuit, i am ussing the Z44N CIRCUIT and i am making a complete test for the motor. RODIN MOTOR is a very…
