Cycloconverter: A variable frequency supply for feeding a three phase motor can be obtained from a cycloconverter which operates on a 50 Hz supply and provides a variable frequency supply…

Harmonic Reduction: The output voltage waveform of an inverter is non-sinusoidal. It contains a rich harmonic content. The Harmonic Reduction cause additional losses and torque pulsations if a three phase…

Charging a Capacitor in Inverter: Charging a Capacitor in Inverter - Inverters are static power converters for converting dc to ac. By controlling the conducting periods of the thyristors it…

Four Quadrants Converters: Four Quadrants Converters - The converters described in the previous sections are suitable either for one quadrant or two quadrant operation. In the former case stepless speed…

Sequence control of Converters: Sequence control of Converters - We have shown that fully controlled converters take lagging reactive power from the mains. This requirement is less in half controlled…

Twelve pulse converter: It is clear from the preceding discussion that increasing the pulse number to six greatly improves the performance of the converter. The ac line current has only…
