Transformer Emf Equation Ppt . The constant “k” is known as voltage transformation ratio. Circuits are separated, as depicted in figure 2, the steady state loop equations are simply: PPT Transformers PowerPoint Presentation, free download from www.slideserve.com Delivery of a good speech along with the given slides would make the greatest of combination. Construction, types of transformers, emf equation, concept of leakage flux and leakage reactance, operation of transformer under no load and on load, phasor diagrams, equivalent circuit, efficiency, regulation and all day efficiency; The main principle of the emf equation of transformer is presented below.
Lm317 Voltage Current Regulator. So in this video, i have explained the following topic of lm317 ic which gives you a clear idea about the lm317 regulator. Typical positive voltage regulator circuit using lm317.
LM317 adjustable current source/regulator from www.imajeenyus.com
According to the lm317 datasheet: Lm317 is a three terminal voltage regulator ic from national semiconductors. Iout = (vref/rh) + iq.
The Ic Is Capable Of Delivering Up To 1A Of Output Current.
By connecting the integrated as shown in the figure, we obtain a current regulator. It requires only two external resistors to set the output voltage. This formula derives from the fact that the voltage between pins 1 and 2 is constant and is 1.25 v.
1 Shows The Lm317 Used As A Series Pass Constant Current Source With A Single Resistor.
From this alone i can tell you that the heat dissipation in the lm317(s) is going to be: It was designed by bob pease, who also worked for national semiconductor. The nominal output voltage is selected by means of a resistive divider.
The Ic Lm317 Is A Voltage Regulator That Supplies Different Output Voltage Levels At Its Output For Incoming Constant Voltage Using A Variable Resistor To Adjust The Output Voltage.
Some said iadj is very low current. It requires only two external resistors to set the output voltage. Moreover, the lm317 module enables you to control different devices like an arduino or an esp8266 (3.3v).
Typical Positive Voltage Regulator Circuit Using Lm317.
The lm337 is the negative complement to the lm317, which regulates voltages below a reference. The regulator ic draws a current limited to 1.5a which is amplified to 5a using a power transistor 2n3055. • complete series of protections:
You Can Also Adjust The Speed Of A Computer Fan Or The Light Intensity Of A Led By Controlling The Output Voltage.
I just want to avoid the heat from the current limiting part. So in this video, i have explained the following topic of lm317 ic which gives you a clear idea about the lm317 regulator. Apart from using it as a variable voltage regulator, it can also be used as a fixed voltage regulator, current limiter, battery charger, ac voltage regulator and even as an adjustable current regulator.
