SCR / Thyristor In Power Electronics – Isolation, Day 14

A talk about SCRs and thyristors in different sizes, packages and from different points in time. A Silicon Controlled Rectifier (SCR) is a unidirectional semiconductor. It is the solid state equivalent of the thyratron (which I showed in this video: https://www.youtube.com/watch?v=odkbxWpQ0ck ) and hence it is also referred to as thyristor or thyroid transistor. In fact, SCR (Silicon Controlled Rectifier) is a trade name given to the thyristor by General Electric Company.

Power Diodes and Diodes In Power Electronics – Isolation, Day 13

A talk about diodes of various sizes, from different ages, development in technology and power levels. The only things missing would be selenium diodes as I forgot where I put them and I do unfortunately not own a mercury arc rectifier.

70 kV / 65 kW X-Ray System, Transformer and Inverter – Isolation, Day 12

I give an overview of a 65kW X-ray generator system for a 70 kV X-ray transformer. The fullbridge of 400A 1200V IGBT bricks makes for a powerful inverter to drive the ferrite cored high voltage transformer.

High Voltage Transformers – Isolation, Day 9

I go through my collection of iron/ferrite core high voltage transformers. MOTs, OBITs, NSTs, PTs and X-ray transformers. Microwave Oven-, Oil burner ignition-, neon sign- potential- and x-ray transformers.

I forgot to add the old and new flyback transformers I have… somewhere…

Induction Heater Power Film Capacitors – Isolation, Day 6

A walk-through of different types of power capacitors that can be used in induction heater applications, ceramic, MICA, various types of film capacitors and extremely large internally water cooled power capacitors are demonstrated.

2 years back I bought a large lot of induction heater capacitors. Buy a 815 KVAr capacitor by contacting me here: https://highvoltageforum.net/index.php?topic=56.0
