A look at a box of IGBTs and MOSFETs that I have salvaged from household electronics like microwave ovens, induction stoves, solar inverters, welding machines, car and battery charges and other common high power electronics with switching inverters. The TO-247 IGBTs can be used in a DRSSTC Tesla Coil using the free half- and full-bridge […]

This is a short teardown of the smallest UPS I have yet found thrown out. The Belkin Regulator PRO Silver UPS 650VA (model F6C650-SER-SB) uses the battery type CSB HC1221W which has been discontinued. If not obvious, my daughter helped me make this video 🙂 Belkin UPS specifications UPS / surge protector 4 power outlets

I do a teardown and test of a Victron Energie Atlas Combi 12-800. It is a combined battery charger and 230VAC inverter. The battery charger of the Atlas Combi is suitable for a 230 VAC, (50 Hz) mains voltage. The charger works automatically, so batteries may remain permanently connected to the charger, even during winter

Test with using regular mineral wool for house insulation, to insulate the work coil in order to achieve higher steel temperatures. Here is another try, unlike the induction heater vertical oven, just with the induction heater horizontal oven. To contain some more heat, accidentally melted some plastic on the enclosure from that

I have constructed a 2200 Watt server power supply made from three individual server power supplies, put in series. This video shows your how to make them run and avoid short-circuit between grounded negative rails. You can check out all the induction heater related videos here: https://www.youtube.com/playlist?list=PLw4xMO1xCMSUOj19zUmFE2-a2lcFBuzX_ This power supply was built to power a

It took some years and someone recently bumping up my old thread about this project for me to write up a article. I had to dig around a bit to find the pictures, make a video and get it on here. Read all about the design and construction of the TL494 flyback driver here: https://kaizerpowerelectronics.dk/high-voltage/tl494-flyback-driver/
