Switch Mode Power Supply

Switchmode Power Supply (SMPS). This has gained enormous penetration of charger markets in the past 15 years, and is now the predominant mode of operation in the telecomms and computer markets. It is lightweight in comparison to Thyristor systems.

 

It consists of fully controllable switching power devices like MOSFETs and IGBTs, and can thus operate at frequiencies much higher than the grid frequency. These devices can be fully turned  on and off at any instant  in time alllowing for precise control of the charger output.

 

A typical SMPS consists of a front end AC-DC rectifier to generate an unregulated DC input voltage, a high frequency chopper that chops the input DC voltage and an output filtering stage to generate a smooth, very low rippple output volage.
