It is unusual however, to find a shunt regulator used as the main regulating circuit in a large power supply. Shunt regulation is only really suitable, at reasonable cost, for relatively small currents and a range of fixed, usually fairly low voltages.

WebHowever real world shunt regulators have limited gain, non-zeroreference input current, and suffer from cathode voltage modulation. This application report derives comprehensive formulas that accurately represent the relationship between the shunt voltage and feedback resistors. It also shows a practical example. Shunt Regulator Limitations WebA shunt is a small resistance that is connected to galvanometer to convert it into ammeter. An ideal ammeter has zero resistance. It is calculated through the formula. S = IGRG / I - IG. Where S is the shunt , I is the maximum current that can be measured using the given ammeter. Also S= IGRG/ I when I >>IG.
