A little Mazzilli driver i lashed up. It is all point-to-point wiring. I used some ultrafast G80n60 IGBTs, a very old .58uf film capacitor, 200v, and the gate pullup resistors are 510 ohms and just a quarter watt! They do get very hot, but they operate within their tolerance range. Inductor is about 100uh, but i do not have an inductance meter to verify. For filtering i had to parallel two 6800uf ‘lyitcs, to share current. Using one, there was too much heat, from quite large ripple current. Now they operate pretty cool. The arcs are about 1.5 times as large as the LOPT, which means the sparks are about 6 inches. This is a small LOPT. I am using 40v input and unknown current. I need to measure that still… Everything stayed cool on this run, except the gate pullup resistors, and the LOPT core.

A worksheet to accompany this video physics.bu.edu This video is a tutorial available in a basic method of analyzing a series parallel combination circuit (a circuit with a battery connected to a series of resistors, both series and parallel circuits have combinations). We want is an example of the method, the client, the circuit to a single equivalent resistor, and then it builds again from the original circuit. At each step of expansion, we canCurrent through and the potential difference across each of resistors.
Physics: Electric circuits. Voltage sources and drops.Current. Current and voltage for circuit elements in series or parallel. Kirchhoff’s loop law; Kirchhoff’s node law. Resistance. Ohm’s law.
