   The media could not be loaded.  This is a great ZVS circuit for building all sorts of high voltage projects (tesla coils, Jacobs ladders, induction heaters, etc.), although you need to know what you’re doing for sure, both for safety (High Voltage!) and just to know how to use it. There are some great online videos about ZVS circuits, and the best one to watch is called Jacobs Ladder Using a ZVS Driver and TV Flyback Transformer, which I followed to build the Jacobs ladder pictured here.I like that this board came with standoffs, so the underside of the board doesn’t touch the desktop (both to not scratch it, and for safety due to the high current flowing through the traces. You can see it’s got some nice thick traces. Unfortunately, the through-hole components were stuffed and soldered in a rather sloppy way, and they don’t look nice, but the board works fine.Note that this version of ZVS board does not have a center tap, but you can still use it with a center tapped transformer, you just have to not use the center tap. As I show in the pictures and video, this works fine. You can clearly see where I just wire-nutted together the two primary coil windings (blue coils) that would join to be the center tap and I just didn’t use it. The ZVS tank circuit still oscillated just fine.My board didn’t get hot while using it. It actually stayed pretty cool, although my flyback transformer (not included) got warm. This was a fun board to play with, and it works great. 5 stars!

   I wanted to create an induction heater and needed a ZVS power supply just like this.This is built really well. The traces are substantial and is durable.There’s nothing special about the coil I used (small ID/OD copper tubing), but it worked great.I wish there was more I could say, but it just works, which is what I needed.

   Sloppy soldering with cold joints. Board will have to be reworked with good flux and a hot iron. Be aware- the transistors on this board only can handle about 55 volts maximum. That means that you can only put in about 16 volts maximum before the transistors fry as switching spikes will be about 3 times your power supply voltage. The transistors are ultra high current types. You will need a very high current supply to make this board work at it’s best. Input and output terminals are completely inadequate for the high current this circuit requires. Be prepared to solder heavy wiring directly to the board and reinforce the larger circuit board traces. The board does come with stand offs which is nice.
