Step 3: Schematics
The "47-200 µH" inductor can be customized to the desired output of the flyback transformer. In general, if you want a higher voltage, the inductor should have an higher value, if you want more current, the inductor should have an lower value. Also, an inductor is a 'must' for the ZVS driver, without it, your ZVS driver may work poorly or not work at all.
Changing the value of the capacitor can also affect the performance depending on the flyback transformer, again, make sure you use good quality capacitor.
