What is the function of the transistor 2N3055 in the circuit?
The 2N3055 transistor is used as a series pass transistor within linear power supplies and also used in high power and medium-current circuits like DC to AC inverters, low-frequency power converters, audio power amplifiers.
Why do we use 2N3055 transistor in regulator?
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.
How do you increase the output current of lm317?
The popular LM317 voltage regulator IC is designed to deliver not more than 1.5 amps, however by adding an outboard current boost transistor to the circuit it becomes possible to upgrade the regulator circuit to handle much higher currents, and upto any desired levels.
How do you make a variable power supply circuit?
This transformer step downs the 220V supply to 24V which is then rectified through a bridge rectifier. The bridge rectifier gives a continuous pulsating DC signal. Then capacitors are used to filter the pulsating signal into a smooth non-pulsating DC. Finally, the voltage is regulated using a regulator IC.
What type of transistor is 2N3055?
silicon NPN power transistor
The 2N3055 is a silicon NPN power transistor intended for general purpose applications. It was introduced in the early 1960s by RCA using a hometaxial power transistor process, transitioned to an epitaxial base in the mid-1970s. Its numbering follows the JEDEC standard. It is a transistor type of enduring popularity.
