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 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…
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…
Step Up Converter or Boost Converter: A Step Up Converter, or boost converter, produces a dc output voltage higher than its supply voltage. In the circuit shown in Fig. 17Â-34(a),…
Step Down Converter: A step-down switching regulator, or Step Down Converter (also termed a buck converter), produces a dc output voltage lower than its input voltage. The basic circuit arrangement…
Use of Efficient Semiconductor Converters: Prior to development of Use of Efficient Semiconductor Converters, inefficient power modulators were employed in several applications. While replacement of these power modulators by the…
Semiconductor Converter Controlled Drives: These are now widely used both in ac and dc tractions involving dc and ac motors, and the conventional drives have all become outdated, and will…
