The output voltage from the ZVS driver and flyback transformer to the plasma torch (quartz tube) was determined using Falstad circuit simulation. It was a circuit, implemented mostly using digital logic chips, with a few timers and other analog components. At the lower left, voltage is shown in green, and current in yellow. p-MOSFET. A high-pass filter passes higher frequencies and attenuates lower frequencies. The transistor does two things: 1) it isolates the zener current from the LED current; 2) it amplifies the zener current so the turn on happens more or less when the zener starts to conduct instead of being a soft turn on. Background To invert the voltage, we will use a device called an inverter built in an integrated circuit (an IC) . Standalone (offline) version of the Circuit Simulator based on NW.
