Here we discuss Discrete Transistor Series Voltage Regulator.īLOCK DIAGRAM FOR SERIES VOLTAGE REGULATOR To maintain the steadiness of the output voltage. Has a control element and Feedback element which help Have one Zener Diode as a source of stable voltage forĬan either have Transistor in series with Zener DiodeĪ Discrete Transistor Series Voltage Regulator Voltage Regulators can be broadly classified into two catagories as Electromechanical and Electronic Regulators. Include additional circuits for protection from short circuits and To maintain a steady output voltage level inspite of AnĮxtreme change in the output voltage may damage current sensitiveĭevices at the load. Generally, fluctuations are observed in the Input Source Voltage. This process reduces the ripple components to a Stores energy when charging and delivers the energy to load whileĭischarging. The working principle of shunt capacitor filter is that a capacitor These ripple components are filtered by passing the output Output of a rectifier is pulsating in nature, it contains large rippleĬomponents. Transformer of small size may be used in comparison with that in The current in both primary and secondary of the supply transformerįlows for full cycle and hence for a given power output, power It has two diodes in series in each conduction path, the peak inverse A bridge rectifier is used here since it is suitable for high Half Wave Rectifier, Full Wave Rectifier and Bridge Rectifier can be Ĭonverts alternating current to direct current byĪllowing the current to flow through it one direction only. That is compatible with the input voltage of the Regulator. The output magnitude of the transformer should be in a range Is used to step down the given voltage to desired Transformer, Rectifier, Filter And Regulator are the basic Load may have current sensitive devices which may get damaged due toĭC output voltage varies with temperature.īlock Diagram of a Regulated Power Supply Poor regulation as output voltage is not constant as load varies.ĭC output voltage varies with the variations in the input voltage. In this work weĭemonstrate their working using Series Voltage Regulator. Voltage Regulators used for the same purpose have theirĪpplications in Adaptors, Computers and Alternators. In the power supply for the devices requiring step-down of AC Mains Line Regulation circuit is an essential component Level on the output channel of a power supply despite changes to the Line regulation is the ability to maintain a constant output voltage
