What This Product Does

SMPS or switched mode power supply is an electronics device that is used to convert AC to DC, AC to AC, DC to DC and DC to AC voltages. The circuit consists of transformer, rectifier, voltage regulator and a filter. The input supply is turned on and off by MOSFETs and outputs a high efficiency, regulated voltage. Like other power supplies, an SMPS transfers power from a DC or AC source (often mains power) to DC loads, such as a personal computer, while converting voltage and current characteristics. In contrast, a linear power supply regulates the output voltage by continually dissipating power in the pass transistor.

Size and weight:

Smaller transformer due to higher operating frequency (typically 50 kHz – 1 MHz). Size and weight of adequate RF shielding may be significant.

Output voltage:

Any voltages available, limited only by transistor breakdown voltages in many circuits. Voltage varies little with load.

Efficiency, heat, and power dissipation :

Output is regulated using duty cycle control; the transistors are switched fully on or fully off, so very little resistive losses between input and the load. The only heat generated is in the non-ideal aspects of the components and quiescent current in the control circuitry.

Complexity:

Consists of a controller IC, one or several power transistors and diodes as well as a power transformer, inductors, and filter capacitors. Some design complexities present (reducing noise/interference; extra limitations on maximum ratings of transistors at high switching speeds) not found in linear regulator circuits.

Radio frequency interference:

EMI/RFI produced due to the current being switched on and off sharply. Therefore, EMI filters and RF shielding are needed to reduce the disruptive interference.

Electronic noise at the output terminals:

Noisier due to the switching frequency of the SMPS. An unfiltered output may cause glitches in digital circuits or noise in audio circuits

Power factor:

Ranging from very low to medium since a simple SMPS without PFC draws current spikes at the peaks of the AC sinusoid.
