Linear Power Supply

A diode bridge, a step down transformer a linear regulator(U1) and some filtering capacitors can be used to build a Linear power supply. This circuit has some advantages such as this circuit has high output current and can give multiple output voltages easily. However it has some disadvantages like this is high standby losses, expensive circuit, and bulky size of […]

Low-Cost AC Supply

Applying the filtered and rectified AC input to a high-input-voltage linear regulator is the simplest way to produce low current level from an AC source. However, it will causes the power dissipation in the regulator. The power dissipation can be reduced by using a switching regulator but it will increases the cost if we use a switching regulator. This circuit […]
