Full wave uncontrolled rectifier with RL load

A Full-Wave Uncontrolled Rectifier with an RL Load converts an AC input into a pulsating DC output using diodes.

Working Principle

• During the positive half cycle, diodes D1 and D2 conduct.
• During the negative half cycle, diodes D3 and D4 conduct.
• The output voltage is always positive due to rectification.
• The inductor causes a delay in current rise/fall, leading to smoother output current compared to a purely resistive load.
• There is a phase difference between voltage and current due to inductance.
