Controlled Transistor Series Regulator Electronic ... Controlled Transistor Series Regulator A controlled transistor series regula­tor is shown in the figure. The circuit is quite similar to that of a simple transistor series voltage regulator except that an additional transistor Q2 is inserted in the circuit. The emitter terminal of this transistor Q2 is connected to the negative terminal of input supply through a Zener diode. Controlled Transistor Series Regulator – Circuit Wiring ... Controlled Transistor Series Regulator. A controlled transistor series regulator is shown in the figure. The circuit is quite similar to that of a simple transistor series voltage regulator except that an additional transistor Q 2 is inserted in the circuit. The emitter terminal of this transistor Q 2 is connected to the negative terminal of input supply through a Zener diode. Zener Controlled Transistor Voltage Regulators – Circuit ... Under such conditions a Zener controlled transistor is always used for maintaining output voltage constant. Basically there are two types of Zener controlled transistor voltage regulators. They are.

The block diagram of a discrete transistor type voltage regulator is given below. A control element is placed to collect the unregulated input which controls the magnitude of the input voltage and passes it to the output. Transistor SeriesVoltage Regulator or Emitter Follower ... Basically there are two types of Zener controlled transistor voltage regulators. They are Series Voltage Regulators Shunt Voltage Regulators. Transistor SeriesVoltage Regulator or Emitter Follower Voltage Regulator Emitter Follower Voltage Regulator A simple series voltage regulator using an NPN transistor and a Zener diode is shown in the figure. voltage regulators series kennethkuhn Series Voltage Regulators 1 by Kenneth A. Kuhn April 4, 2009, rev. April 14, 2013 Introduction The most common form of analog voltage regulation is known as series because the control element (a transistor) is in series with the unregulated voltage source and the load. VOLTAGE REGULATORS IDC Online A zener controlled voltage regulator is used when the efficiency of a regulated power supply becomes very low due to high current. There are two kinds of zener controlled transistor voltage regulators. Zener Controlled Transistor Series Voltage Regulator Such a circuit is also named an emitter follower voltage regulator. It is called so because the Regulated Power Supplies Learn About Electronics Power supplies. Series voltage regulators explained. Simple series regulators, zener diode action, feedback, current limiting and over volts protection. Learn about electronics ... As Tr3 is connected across the base emitter junction of the main control transistor Tr1, the action of turning Tr3 on will reduce the base emitter voltage of Tr1 by ... Chapter 6: Voltage Regulator Ajlon Technologies Transistor Shunt Regulator The control element is a transistor, in parallel with the load. While, the resistor, R S, is in series with the load. The operation of the transistor shunt regulator is similar to that of the transistor series regulator, except that regulation is achieved by controlling the current through the parallel transistor Linear regulator Adding an emitter follower stage to the simple shunt regulator forms a simple series voltage regulator and substantially improves the regulation of the circuit. Here, the load current I R2 is supplied by the transistor whose base is now connected to the Zener diode. Thus the transistor's base current (I B) forms the load current for the Zener diode and is much smaller than the current through R 2.
