This type of rectification process is mostly seen in all power supplies of modern-day electronic and electrical apparatus. In such cases, Power Semiconductor Diodes are used to overcome the excess currents and voltages.Ī Power Semiconductor Diode is a crystalline semiconductor device, also known as Power Diode, used mainly for the purpose of rectification. This process of current conversion is called as Rectification and the circuits used are called Rectifiers.īut due to the large amounts of forward current and revere bias voltage, small signal diodes may be overheated and get damaged in the process of rectification. Small signal diodes conduct current solely in one direction: from anode to cathode and this is the most important property used in converting alternating current to direct current. We know that small signal diodes are used in several applications like current steering, over voltage protection, switching circuits, clipping circuits, clamping circuits, snubbing the small duration waveforms and the most important of all: power conversions (from AC to DC).
