Power supply regulation technique in which the regulating device (typically a transistor) is placed in series or parallel with the load. Voltage variations across the load are controlled by changing the effective resistance of the regulating device to dissipate unused power. Also see Series Regulator, Shunt Regulator and Post Regulation.
The percentage change in output voltage due to a change in input voltage level. This is usually a measurement of the output deviation as the input voltage is varied from low line to high line.
The change in DC output voltage when the AC input voltage is varied through out its range while the DC load is held constant. In switchers, this can be 90 to 264 volts AC unless otherwise specified. In linears, it may be as limited to 108 to 132 volts AC.
The change in output voltage when the AC input voltage is changed from minimum to maximum specified. It is usually a small value, and may be near zero with current mode control.
The change in output voltage in percent as the input voltage is varied over its specified limits, with load and temperature constant.
The change in a converter's output voltage due to a change in the input line voltage, usually expressed in percent over a specified input voltage range.
Line regulation occurs as the result of output voltage variance caused by input voltage variance. This is defined by the maximum amount of percentage change in output voltage as input voltage varies in a specified range.
Line reguation means that the power supply will provide a constant voltage as the input voltage varies. Inexpensive transformer based wall mount power supplies, for example, do not have good line regulation, and will change the output proportional to the input voltage. Switching power supplies, by their very nature, have very good line regulation. This has a plumbing analogy. When you are taking a shower your spousal unit usually takes the opportunity to flush the toilet. This causes the cold water pressure to drop, and thus the flow of cold water in your carefully designed mix drops and you are scalded. Then, as if to compensate, the sink faucet is turned on full hot and an analogous phenomenon causes you to freeze. We power supply designers would say that the line regulation of your shower head is not adequate.
The variation of an output voltage due to a change in the input voltage, with all other factors held constant. Line regulation is expressed as the maximum percentage change in output voltage as the input voltage is varied over its specified range.
The change in output voltage, in percentage, as the input voltage is varied over its specified limits, with all other parameters held constant.
The change in a converterÕs output voltage resulting from a predefined change in the input voltage, expressed as a percentage of the output voltage.
The percentage change in electrical output die to the input voltage varying over limits, at specified load values, with all other factors constant.
Change in output voltage due to varying input voltage. Expressed as a percent of the normal output voltage, a power supply with tight line regulation delivers optimum voltages throughout the operating range. This is tested by measuring the difference in output voltages while varying the input voltage from minimum to maximum, i.e., from 85 to 135 volts.
The change in value of DC output voltage resulting from a change in AC input voltage over a specified range, or from low line to high line or from high line to low line. Normally specified as the + or - change from the nominal DC output voltage.
The percent change in output voltage for a given change in line (input) voltage. A rating that indicates the change in regulator output voltage that will occur per unit change in input voltage.
The ability of a voltage regulator to maintain a constant voltage when the regulator input voltage varies.
