What is switch mode power supply (SMPS)?
Switch Mode Power Supply (SMPS) is an efficient power supply that converts electrical power using switching devices that turn on and off at high frequencies and energy storage components like inductors or capacitors to supply power when the switching device is in its non-conduction state.
What is a switching power conversion technique?
A switching power conversion technique where the on-line (or width) of a duty cycle is modulated to control power transfer for regulating power supply outputs. A switching-mode power supply topology which utilizes a center-tapped transformer and two power switches. The two switches are alternately driven on and off.
How can a power supply be customized without changing component values?
The different thresholds and limits are also defined in the software as variables and their value can be modified easily. Through this mechanism, many operating parameters of the power supply can be customized without ever changing any component value in the circuit.
How does a switching power supply work?
Switching power supply uses a high-frequency transistor to chop the high DC voltage (rectified from AC source) into high AC voltage and converts it into a desired voltage by a high-frequency transformer, and then rectifies and filters the voltage to a DC level.
What is included in a switching power supply manual?
This manual includes basic information for switching power supply, general specifications, safety regulations, EMC standards, CE, reliability, operation notes, technical Q&A, and notes on failure correction.
How does a power supply design work?
The power supply designer has no option and in most cases it requires a significant amount of external circuitry to circumvent some of the built-in features of the controllers. By the introduction of a digital engine such as a μC or DSP, the decision, how to react to certain conditions becomes user programmable.
