Get know about a rectifier circuit and how it works


A rectifier is a well-known electronic device designed to convert Alternating Current (AC) to Direct Current (DC). The rectification is a process that converts AC to DC to follow in only one direction. The main purpose of this process is to straighten the direction of the current. There are loads of physical forms of rectifiers in our time. However, the most outstanding forms of the best rectifier are as follows.

  • Mercury arc valves
  • Vaccum tube diodes
  • Semi-conductor diodes
  • Silicone based semiconductor switches

The following details assist you to enhance your expertise in the rectifier circuit and how this circuit works.

What is a rectifier circuit?

A power supply is required to provide power to any circuit and power electronic devices from an AC supply. A rectifier is used to convert AC to DC and give only single way flow of electrons.  There are many types of rectifier diode circuit in our time. However, the ordinary form of rectifier circuit is the middle path rectifier. This circuit lets one path of an alternating current to pass from end to end load.

A step-down transformer in the circuit is used to step down the high AC input voltage to the lower AC voltage that has to be inputted to the rectifier. There are two separate coil windings used in this transformer with various numbers of turns. AC voltage is measured between two terminals in the secondary winding.

How does a rectifier circuit work?

A rectifier diode in electronics is used to convert the household alternating current into direct current used as an alternative to usual batteries. A set of interlocked diodes is used to make the rectifier circuit that converts alternating current to direct current.

The voltage in the household current is swinging from the positive to negative side in proper cycles repeatedly in the range of 60 times per second. The negative side of the voltage cycle can be eliminated soon after a diode is placed in series with the alternating current voltage.

This is worthwhile to focus on the waveform of the voltage from the rectifier diode and ensure that intervals that change between a short voltage increase and periods of no voltage. This direct current forms as only positive voltage. On the other hand, this element pulsates in terms of on and off.

A single diode has the best stuff to rectify the voltage to a half of the time.  The positive voltage attains the highest level as the input voltage. However, the average level of the rectified voltage is only the half the level of input voltage. This rectifier circuit is known as the half-wave rectifier. This is mainly because it passes only along half of the incoming AC waveform in a proper manner.   The net effect of the best bridge rectifier includes both halves of the AC sine waves allowed to pass through it. However, the negative half of the wave is inverted and becomes positive.
