Figure 3.. Full-wave bridge type Unltered Power Supply. In most of the countries electrical power is transmitted as a sinusoidal AC voltage. We often found TL431 in switching power supplies, battery chargers, voltage digital, etc. 14 0 obj <> endobj The power supply's isolation between input and output or chassis comes from the isolation provided by the supply's transformer. We recently asked ourselves the following question: all USB chargers are probably not equivalent in terms of efficiency, but up to what point? Uses industry popular LM317 in TO3 package for delivering variable output voltage. from an AC voltage source, we can pass the input signal through a nonlinear circuit, and alter the, We know that diodes are nonlinear circuit elements and they can be used, An example of a diode rectifier circuit known as the half.
