We need a 3Phase Bridge SCR driver (6 SCR) for a DC bus voltage controller & a Battery Charger.
Analog & Micro controller based both are acceptable but priority is analog ic based circuit. Input Line voltage 380V - 460V & 280V - 340V.
Maximum (Short circuit) current ratings 200A.
Following features must be included:
1. Over voltage & under voltage protection
2. Short circuit & over current protection
3. 1 phase loss protection
4. Over temperature protection
Components that can be used:
Comparator, Micro controller, MosFET, Transistor, Pulse transformer etc. You can advice if any other is required.

Hi, I have experience in Power Electronics Circuits. Your circuit won't be hard. I can do it with microcontroller you want using mosfets + the protection components.
