Btw, recently I have some time to come back to analysing ZVS oscillator which I have tested before.
New problem struck me on how do I connect any salvaged transformer from electrical appliances to ZVS whereas the transformer is having single winding primary and not centre tapped one?
To solve this, I have made a modification on the original ZVS driver; by swapping the centre tapped coil with centre tapped capacitor/ double capacitors. Which means that, this new driver's output can be fed directly to any primary of salvaged transformers which mainly consist of single winding primary and not the centre tapped one.
Here is the modified ZVS circuit;
Thats all!
Hello,
ReplyDeleteI'm wondering, have you tested the modified ZVS driver circuit (with the two capacitors in series), and if so how well does it work?
An apparent advantage of that circuit would be that no dc current can flow if there is a fault.
hi, can you show the result ? is the spark is stronger or weaker than center tapped coil ? i see in other website, they use 2 coils choke for each side of the coil to avoid center tap. but i think their method will less efficient, because each time the fet is closed, 1 coil will send current directly to negative terminal.
ReplyDeleteHi. C1 must be equal to C2. If C1>C2, then the capacity will be C2, because both capacitors are in serial configuration. So you can put C1 and C2 with different values, but the circuit will work like if you put two identical caps with a capacity equal to the lower capacitor capacity
