Talking about rectifiers, it is an electronic device that works to convert AC current to DC. Rectifiers are used in many circuits. Wherever we have to change the AC to DC voltage, we have to use a rectifier. This rectifier uses a diode to convert such supply to DC or you can say that diode is used to make rectifier. And there are mainly 2 types of rectifiers. When voltage is given by the transformer on the rectifier, it is both a positive and negative cycle but it only allows Positive Half Cycles to go forward due to rectifier diode. And stops the negative Half Cycles. Let's know more about Rectifiers In Electronics Engineering.
