Line Regulation Formula For Smps
Most standard desktop smpss available today seem to be rated for at least 400w and very rare few at 250w which btw seem quite expensive. Voltage regulation in a switching power supply is made without dissipating excessive amounts of heat.
The step down transformer in an smps operates at a high frequency which in turn reduces its volume and weight.
Line regulation formula for smps. Load regulation is the capability to maintain a constant voltage or current level on the output channel of a power supply despite changes in the supplys load such as a change in resistance value connected across the supply output. A well regulated power supply can have a line regulation of less than 01. Output resistance the output resistance of a power supply determines the load regulation.
The line regulation is defined as. It could be expressed in or actual voltage change in the output voltage relative to allowable input line voltage range. Load regulation is the ability to maintain specified output voltage over changes in the value of the load.
Load regulation is the measure of the ability of a power supply to maintain a constant output voltage despite changes in output current or load. This can cause malfunctioning of appliances or even short circuiting. Currents and circuits should be measured around a house from time to time to determine whether the line regulation is too high for a given section.
A good load regulation ensures that the power supply will deliver a required and stable voltage to the circuit or system. It is expressed as percent of change in the output voltage relative to the change in the input line voltage. Line regulation is the ability to maintain specified output voltage over changes in the input line voltage.
This allows a switching power supply to enjoy a much smaller form factor than linear regulators. Performance of the power supply. 100 v v v line regulation ll hl ll where v hl load voltage with high line v llload voltage with low line the smaller the line regulation the better the power supply.
Line regulation is the ability of the power supply to maintain its specified output voltage over changes in the input line voltage. Is there something significantly different between such smpss and some of the other smpss found on electronics distributor sites which seem to supply.
