Hi,
Im not sure if this topic is still open but i would like to build a pure sinewave inverter using some old thyristor packs from some motor softstarters, semikron - SKKT 92B & INXS MCC 95.
Im new to inverters, but i do come from a electrical background and i do understand the risks involved in working with high dc voltages.
please could someone assist me with a circuit diagram for pure sinewave inverter making use of semiconductor thyristor packs instead of mosfets/transistors/igbt's if that is possible.
the project is to go fully transformer-less, using dc battery supply to whatever voltage required to make this work well (about 380 vdc input)
any help would be appreciated.
thanx in advanced
kind regards
trevor.

- use either the Semikron SKKT 92 Amp or INXS 95 Amp thyristor packs,
- yes i know i could purchase a commercial product, but the reward of building it is so much greater.
- cooling for the thyristors wont be a issue as i have the heatsinks with forced cooling.
- any means to log the input/output voltages/currents etc (arduino mega 2560) or ATMEL microcontroller chip?
- control the inverter via the arduino? or ATMEL microcontroller chip?
- load approx 5Kw peak @ 230vac, avg current @ 10amps. we have load shedding on our powergrid daily spanning for 4hrs at a time.
- later i plan to add a solar pv and charger circuit with monitoring.
any help would be appreciated.
