Switch Mode Power Supplies (SMPS) are used in a range of applications an efficient and effective source of power. This is in major part of their efficiency. Power supplies provide the necessary power, voltage and current requirements for electronics devices. They usually changes AC to DC voltage. SMPS offers Advantages in terms of size, weight, cost, efficiency and overall performance. These have become an accepted parts of electronics devices. There are some Disadvantages in SMPS like Noisy, External Component, Expert design required and Filtering. It is a device in which energy conversion and regulation is provided by power semiconductors that are continuously switching ON and OFF with high frequency.
Basics concept of SMPS:- The Basic concept of SPMS is the fact that the regulation is undertaken by using a switching regulator. This uses a series switching element that turns the current supply to a smoothing capacitor on and off. An SMPS consists of a Transformer which steps up or down AC voltage, A Rectifier Diodes which changes AC to ripple DC, A filter network includes capacitor and inductor for smooth out the ripple and a voltage regulator which keeps the voltage constant.
Types of SMPS:- There are some well known and commonly used Switch Mode Power Supply (SMPS) for end customers.
1. DC to DC Converter: - A DC to DC converter is an electronic circuit that convert a source of direct current from one voltage level to another.
2. Forward Converter :- A forward converter transform a DC voltage at the input to the DC voltage at the output.
3. Fly back Converter :- The flyback converter is used in both AC/DC and DC/DC conversion with
galvanic isolation between the input and any output.
4. Self Oscillating fly back Converter :- Self Oscillating flyback converter is a type of flyback converter which doesn’t require a separate oscillator but the switching of primary current is achieved by a built in self oscillatory action.
