Step up Step down Chopper or Buck Boost Converter - Working Principle: A chopper can also be used for stepping up or down the supply voltage by varying its duty cycle. This is also known…

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 the output of a chopper…

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 converter. So the filtering…

Single Phase Dual Converter Circuit Diagram with Four Quadrant of Operation: We have seen that Single Phase full Converters with inductive loads allow only a two-quadrant operation. If two of these full converters are connected…

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, therefore, the effective value of…

Single Phase Half Wave Controlled Rectifier with Resistive Load and Inductive Load: In a Single Phase Half Wave Controlled Rectifier only one SCR is used in the circuit. It is included in between the ac…

What is a Power Converter? Solid-state power converter are employed for obtaining the appro­priate form of electrical energy such as direct current or adjustable-frequency alternating current (required to operate most electronic circuits and motor drives)…
