Why do we use 2N3055 transistor in regulator?
Why do we use 2N3055 transistor in regulator?
12V DC regulator circuit using 2N3055. It is a series voltage regulator because the load current passes through the series transistor. As the circuit diagram below, The input terminal wants an unregulated DC supply,15V to 20V. Then, the regulated voltage will come out to the load.
What is the use of 2N3055 transistor?
The 2N3055 remains very popular as a series pass transistor in linear power supplies and is still used in for medium-current and high-power circuits generally, including low frequency power converters although its use in audio power amplifiers and DC-to-AC inverters is now less common and its use in higher frequency …
How is regulated power supply calculated?
Load Regulation – The load regulation or load effect is the change in regulated output voltage when the load current changes from minimum to maximum value.
- Load regulation = Vno-load – Vfull-load.
- % Load Regulation = [(Vno-load – Vfull-load)/Vfull-load] * 100.
- Minimum Load Resistance = Vfull-load/Ifull-load.
Which transformer is used in regulated power supply?
A step-down transformer has a large number of turns on its primary (input) coil which is connected to the high voltage mains supply, and a small number of turns on its secondary (output) coil to give a low output voltage.
What is called regulated power supply?
A regulated power supply is an embedded circuit; it converts unregulated AC (Alternating Current) into a constant DC. Its function is to supply a stable voltage (or less often current), to a circuit or device that must be operated within certain power supply limits.
How do you regulate voltage and current?
To maintain a steady voltage level regardless of the amount of current drawn from a power supply, the power supply can incorporate a voltage regulator circuit. The voltage regulator monitors the current drawn by the load and increases or decreases the voltage accordingly to keep the voltage level constant.
How many amps does a 2N3055 power supply deliver?
By using two 2N3055 transistors we become more then 2 times the amount of amps then the power supply delivers, making it real though to brake ;). Although you could use this design to deliver 20 amps (with almost no modifications and with a proper transformer and a huge heat sink with a fan), I did not needed such much power.
Why do you need a voltage regulator using 2N3055?
You want to use a DC regulator or learn about voltage regulators using 2N3055. Why use this transistor? Normally, it can be used with loads that require a current not exceeding 2A and a voltage of not more than 30V. This is enough for general work. It’s a transistor that people like to use for a long time. Therefore easy to find And very cheap.
Is there a 0-30v 0-5a power supply circuit?
0-30V 0-5A regulated variable power supply circuit. This is 0-30V 5A variable benchtop power supply circuit, with voltage and current adjustable system. The output voltage 0-30V and a maximum current of 5A. Use LM723 as a voltage regulator designed primarily for series regulator applications. By itself, it will supply output currents up to 150 mA.
How many transistors are needed for LM723 voltage regulator?
Use LM723 as a voltage regulator designed primarily for series regulator applications. By itself, it will supply output currents up to 150 mA. So need to use two transistors 2N3055 for boost up current to 5A.
