Careful circuit design has resulted in outstanding load and line regulation, comparable to many commercial power supplies. Keywords CMOS analog integrated circuits. They are exceptionally easy to use and require only 2 resistors to set the output voltage.
#Power transistor voltage regulator series#
Fundamentally, the transistor voltage regulators which are controlled by Zener are classified into two types namely series voltage regulators and shunt voltage regulators. Transistor level simulations confirm the effectiveness of the proposed approach. In prior emitter-follower voltage regulators, zener diodes, which have the characteristics of good voltage regulation and low-current requirement, have been. Beneath these conditions, a transistor-like Zener controlled is used frequently to maintain o/p voltage stable. Thus, the Zener RPS ( regulated power supply)efficiency turns into extremely low as the load current is high. Half-BridgeAtwo-transistorconverter usedinmanyofflineapplications. It is not simple to modify the o/p voltage because no such resources are provided. Push-PullAtwo-transistor converterthat isespeciallyefficient at lowinput voltages.This occurs due to both VZ & VBE reduce by the rise in room temperature. The adjustments within Zener current are decreased to a significant amount the amount produced is not completely stable.The series voltage regulator disadvantages are listed below. Therefore, the Zener impedance effect will be decreased extremely & we can get an additional stabilized output. Zener Controlled Voltage Regulators can either have Transistor in series with Zener Diode or in parallel with Zener Diode. In case it doesnt, a diode can be connected across the input/. The main benefit of this voltage regulator circuit is, the changes within Zener current are decreased through a factor ‘ß’. Instead of conventional PMOS linear regulator topology, a NMOS power transistor is chosen as the pass device on considerations of smaller silicon area and. When power is shut off to the regulator the output voltage should fall faster than the input.The advantages of this series voltage regulator are listed below.
