  • Rectifier Transformer - Working Principle and Application

    2015-11-25 · A Rectifier transformer is a special application transformer which includes diodes and thyristors in the same tank. Power electronic circuits that convert alternating current (ac) to direct current (dc) is called rectifier circuits. Similarly, the circuits which can convert direct current to alternating current are called inverter circuits.
