DESIGN AND STUDY OF SINGLE-PHASE / THREE-PHASE DIODE BRIDGE RECTIFIER

Rectifier is an electronic circuit that converts an input AC voltage into a DC voltage at the output terminal. Our lab conducts thorough experiments for

  • Understanding the principle of operation of a diode bridge rectifier to convert alternating current (AC) into direct current (DC)
  • To study the effect of different types of filters on output voltage
  • Analysis of input current variations, power factor, and total harmonic distortion (THD) with different filters.
  • Understanding the single-phase grid-side requirements in terms of THD and power factor and the need for power factor correction

DESIGN AND STUDY OF SINGLE-PHASE / THREE-PHASE BOOST PFC CIRCUIT

Power Factor Correction (PFC) shapes the input current of the power supply to be in synchronization with the mains voltage, in order to maximize the real power drawn from the mains. The three phase boost PFC circuits have many applications such as  energy storage systems, Electric Vehicle (EV) charging, high power applications. This experiment helps in

  • Understanding the principle of operation of a single-phase Boost PFC.
  • Understanding the principle of operation of a three-phase PFC circuit
  • Analysis of the boost PFC under different control techniques.
  • Achieving unity power factor by using closed-loop control.
  • Selection and Sizing of passive components
