Working in a power testing laboratory, performing type tests on medium voltage and high voltage equipment (such as power transformers, instrument transformers, medium voltage circuit breakers and switchgears, high voltage disconnectors, insulators, etc.) requires readiness of the laboratory equipment and the human operators. Actually we perform the tests using classic electrical equipment like power transformers, changing ratio manually, and controlling manually all the electrical parameters like voltage, frequency. We wish to implement a general purpose yet specialized power inverter to achieve the same results with a lot less effort, increasing productivity and earnings for the laboratory. The result of the inverter implementation can be shared with SIEMENS factories to improve their factory acceptance tests capability also. In attachment you can find a scale simulation of an asymmetric power fault current achieved through Arduino Uno board using PWM modulation and a totem-pole inverter using a couple of complementary NPN and PNP BJTs.
This idea will get three TAPAS dev kits.
