Switch-mode power supplies (SMPSs) are frequently used to provide the various levels of DC output power needed for modern applications, and are indispensable in achieving highly efficient, reliable DC-DC power-conversion systems. Why SMPS? The majority of electronic DC loads are supplied from standard power sources.


Ac Dc Switching Power Supply Schematic

Power supply unit (PSU) usually works to convert utility AC voltage into regulated DC voltages to be used by the equipment. In most PSU, the energy flow is controlled with semiconductors which are continuously switching on and off with high frequency. Such kind of PSU are referred to as switch mode power supplies or SMPS .

There are two main reasons, and both relate to cost. First, linear power supplies require large and expensive transformers. Second, the regulating transistor generates a lot of heat, which requires large and expensive heat sinks. For example, a 50V variable power supply set to output 5V at 2A might have (50V - 5V) * 2A = 90W of heat to dissipate.

Introduction to Switched Mode Power Supplies. SMPS circuits are considerably more complex than the linear stabilised power supplies described in Power Supplies Module 2. The main advantage of this added complexity is that switched mode operation gives stabilised designs that can deliver more power for a given size, cost and weight of power unit.
