    • 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 ...

    • Optimization and efficiency improvement of rectifiers with intephase transformer 

      Kudzai, B. C.; Munyaradzi, C. R.; Didmus, T. M.; Rajkumar, P.; Bukelani, Musiiwa P. (БНТУ, 2025)
      In this paper, operation of twelve pulse rectifier transformer with interphase transformer is presented and simulated implemented 12-pulse IGBT rectifier system. A 35k A, 450 V rectifier transformer is analysed and investigated focusing on performance and harmonic analysis of power converter system. This design results tends to reduce of harmonics of utility line current. Power ...
