Work out amps from kw Videos

The OVERTUNITY demonstration generator work amplifier (In 1.3KW Out 1.5KW)

the generator produce (380v x 3 a x0,8pf x1.732):1000=1,5kw ,,, consume 6 amps in 230 volt =1,3 kw ..thank you,

Hi

600 watt induction heater

Haven't made a video in a while, mostly because I've been failing to make an induction heater that doesn't blow up after a few minutes. Turns out the Mazilli ...

I cannot believe that you got to 400 amps with this low power, and I also afraid that you current probe is not designed for this high frequency. When you have 3,29uF and 71kHz, your capacitive reactance is about 681 milliohms. So the math is 400A*0,681ohm = 272V. If you measure 272V at 71kHz across you caps, then it's really 400 amps sloshing around. I have a tank circuit with 5uF and 45kHz so it has 707 milliohm reactance, almost the same :D I need 550W to get 200A and 2200W for 400A in idle! Here are measurements of my tank circuit's current and voltage, with the wattage needed to hold it (empty coil). Power-W | V | A 8700 | 560 | 800 2200 | 280 | 400 1088 | 210 | 300 550 | 140 | 200 136 | 70 | 100 34 | 35 | 50

Sure, ideal resonance would get stronger and stronger indefinitely, so it all depends on the copper and caps resistance, certainly your tank circuit must be just less lossy.Second thing, what voltage do your switches see? It looks like fullbridge where the high side was replaced by inductors, what happens on 100V then? is it getting higher?

+Durchgebaut Never underestimate the power of resonance. The probe is a proper 'scope current probe and is rated to 100kHz so that value is most certainly correct.

+High Voltage They're IGBTs and a kind of mutant Mazzilli/half-bridge. Schematic and a bit more detail here: //imgur.com/TT94SjnQuite liking this design for the oscillator over a regular half-bridge as I can still use n-channel devices, but no messy high side switching.

alex993cc1 commented on 28 Mar 2016
nice progress. i see you changed over to some real macho mosfets LOL. if you build the PLL driver you can actually get it to track tank resonance and do all the tuning for you as the workpiece heats the frequency changes a bit. I really need to get off my arse and do some more work on mine but other projects keep getting in the way, good stuff

alex993cc1 commented on 28 Mar 2016
+gristc CD4046 can run it for you. you can even do current limiting to do your temperature control, or if you go the MCU route possible phase angle control using SCRs as your input rectification. check how fast the CM300 modules are, you might find you will need a huge capacitance to get the frequency low enough. i have some CM400s and some semikron half bridge bricks and neither of them are fast enough unfortunately :(

gristc commented on 28 Mar 2016
+alex993cc1 Hehe, thanks. Looking at something PLL like for the driver, possibly MCU based though as my final goal is to have temperature control over the crucible. I messed up in the commentary though, they're actually IGBTs in the beefier version. IXGN60N60s so I should be able to push a fair bit more power though them once I get proper ZVS switching happening.Then to play with the CM300s. :D

Okay: I bought this thinking these were the original sounds (my mistake lol). I really want these sounds and physics, but i dont know how to go about doing this (intsalling them). I downloaded the .rar file, and that is as far as i could understand the directions. Could you possibly tell me what to do in a simpler way? I am new to mods.
