Skip mazzilli zvs content The ZVS flyback drivermade popular by Vladimiro Mazzilli, is one of the most efficient and powerful flyback drivers used by high voltage hobbyists from all over the world. Internal connections The second main mazzilli zvs is the resonant capacitor. Especially when you power up the circuit you will want to be sure that the gap is small enough so it is arcing before pulling the wire apart. Best luck, Sieu.

With this ZVS circuit you do not really control how much current it draws, if your supply can only deliver 10A, there is a great risk it will overburden the power supply, pull the voltage down and your MOSFETs explode due to not switching properly at the low voltage. Can u help me with it. Thanks, Harsh. It sounds like you have a short circuit, revise your circuit vs. Hi Mads I did revise the circuits and i found out that the inductor was faulty. Just letting you guys know an important fact about ZVS drivers.

They do not like it when the power supply slowly increases from zero to its rated output voltage, which is typically what happens when a DC power supply is turned on. That could cause a condition in which both FETs are conducting at the same mazzilli zvs.

It is preferable to mazzilli zvs the voltage source disconnected from the ZVS driver while turning on the power supply, and then after a second or so, connect the power supply to the ZVS. The fast risetime voltage will ensure that one of the FETs will conduct before the other one does, and oscillation will then start. Hi everyone. I really appreciate your openness and willingness to collaborate here.


The information has been extremely helpful for me! I would not omit the zener diodes, there can still be mazzilli zvs spikes which are voltage transients that are high enough voltage and have enough energy to damage the gate of the MOSFET.

It can properly run down to some kHz, not that Mazzilli zvs have tested it, but its an assumption based on time needed to switch state. I would however mazzilli zvs build something that switches below 20 kHz, as it gets in the audio range of what we can hear.


Hi everyone I managed to get double the output from my circuits with 2 flybacks hooked up in parallel to the mazzilli zvs and the flybacks output in series. And if not could you recommend me an alternative setup that can be used with this batteries? So you just have to add enough batteries in series mazzilli zvs obtain at least VDC.

Skip to content. Note: if you mazzilli zvs wondering why I put ohm resistors before the UF, I saw with the oscilloscope that placing those resistors reduced the noise coming to the inputs of the TPSP. This is because those resistors delay a bit the turning mazzilli zvs process of a Mosfet. This prevents the scenario where the Mosfets are switching and we can't consider that one of them is fully turn on, so the uH inductor creates a peak of voltage to both drains.

I was planning on using a modification of the circuit I saw in which the center tapped coil is replaced with a non-center tapped coil and two choke inductors mazzilli zvs used one to feed the each side of the coil. However I am skeptical that this would work based on the explanation given here. Is there a way to have the work coil not neter tapped — its pretty hard in my set up to amke the work coil center tapped? Will using normal 9 Mazzilli zvs batteries work? What about a DC power supply?

How to Build a Simple But Powerful Flyback Driver

Figure 1 shows the Mazzilli ZVS flyback converter circuit. This circuit, which was invented by Vladimiro Mazzilli, is an improvement of Mazzilli zvs Oscillator topology [18]. The design combined two Mazzilli ZVS circuits where each CRT flyback was driven by single Mazzilli mazzilli zvs.
