Inverter - Definition and Classification of Inverters: A device that converts dc power into ac power at desired output voltage and frequency is known as an inverter. Some industrial applications…
Three Phase Cycloconverter - Types, Working and Applications: A cycloconverter converts ac at one frequency to an ac of another frequency. Cycloconverters can be classified as single-phase to single-phase, three-phase…
AC Regulator - Definition and Classification: An ac regulator converts a constant ac voltage into a variable ac voltage of the same frequency. No doubt, ac voltage level can be…
Step Down Chopper with RLE Load Working Principle: The choppers are widely employed for speed control of dc motors in industrial and traction drives. Figure 27.30 (a) shows the basic…
Step up Chopper - Definition, Circuit Diagram and its Working Principle: In a step-down chopper the output voltage lies between zero and supply voltage. However, there are techniques by which…
Three Phase Converter Circuit: For large sized (rating exceeding 15 kW) motors 3-phase drive is employed. The output voltage of a 3-phase converter has less ripple contents than that of…
Single Phase Full Wave Controlled Rectifier (or Converter): In case of Single Phase Full Wave Controlled Rectifier (or Converter) both positive and negative halves of ac supply are used and,…
What is a Power Converter? Solid-state power converter are employed for obtaining the approÂpriate form of electrical energy such as direct current or adjustable-frequency alternating current (required to operate most…
