    • Design and construction of 12 V DC to 220 V AC power inverter 

      Munyaradzi, C. R.; Tatenda, M.; Bukelani, Musiiwa P.; Rajkumar, P.; Vikneswaran, V. (БНТУ, 2025)
      The purpose of this project is to design and construct a 12 V DC to 220 V AC inverter using components such as the TL494 PWM IC, MOSFET and a center tap transformer. The TL494 will serve as the oscillator responsible for generating a 50 Hz alternating electromagnetic field. The TL494 will be configured to produce a wave output at the desired frequency of 50Hz. This wave will be ...
