So I'm not sure about the MOT route, but I'd certainly get the power.

I've seen quite a few half bridge flyback drivers based on a tl494 chip for pulse width modulation, which controls power, would that be sufficient for current limiting? Or would I need some form of feedback? Would rectifying the output from my large AC flyback cause any problems?ĪNother option I've been thinking about it a microwave transformer, as a large one has plenty power and some have magnetic shunts which act as a limiting, from what I've heard, or I could use another as ballast, however I'd need to step up the voltage with about 4 stages, and I want to minimise high voltage components as that's when it gets expensive, and that could also end up with lots of current ripple. I'd rather not use a ballast resistor I don't want to waste so much power.

As it is I have one very large AC flyback, a few medium sized DC flybacks and an 8 amp 230 volt variac, I know that the ZVS driver is more than capable of 500 watts, but is there a way of limiting the current output easily? Does the air gap i the transformer do this? And if i go down the ZVS route what value components will I need? I had my large AC flyback running at 500 watts for a bit then my driver broke, and I don't know why. The problem is that the laser tube has negative resistance once the arc has struck, so I either need a current limited PSU, or a big ballast resistor, from what I've heard. The arc length will be roughly 400mm, and for the power supply I'm aiming for about 10-15kv DC at 500 or so watts. I'm planning on building a small co2 laser as part of my A levels, I have pretty much most things clear in my head other than the power supply, and I can't find a neon sign transformer at a price I can pay anywhere.

We will place your name on the thanks list and you'll be helping to keep 4hv.org alive and free for everyone. Unfortunately, this server costs and we rely on the help of site members to keep 4hv.org running. But not being a Double-E major I’m having to educate is hosted on a dedicated server. This site’s article provides me with the basic information I need. PROBLEM: There is no such beastie on the market. SOLUTION: Get a photocell switch that disconnects the controller from the panels after Sunset and reconnects after Sunrise. When I disconnect the controller from the panels and reconnect it, then it works just fine. Instead of reading 14V going into the battery array, they read 24V and the batteries don’t charge. When the Sun comes up the next morning, the controllers ‘misbehave’. However several lines of PWM controller units all have the same problem. SITUATION: Solar Panel Controller doesn’t function properly after the Sun comes up.īACKGROUND: At a remote mountain location, I have a solar panel array to provide electrical power.
