Single Phase Full Bridge Inverter: The main drawback of half-bridge inverter is that it requires 3-wire dc supply. This difficulty can, however, be overcome by using a single phase full…
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 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…
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,…
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…
Light Activated SCR (LASCR) - Symbol, Construction and Operation: Light activated SCR is just an ordinary SCR except that it can also be light triggered. Most LASCRs also have a…
