In this case, the voltage drop occurred on the line V Z = E C − E S − V C is greater than the regular voltage drop V L. The compensation process increases the current flowing on the line according to the situation before compensation that proves the series compensation is essential to increase the delivered power.
In this case, the voltage drop occurred on the line V Z = E C − E S − V C is greater than the regular voltage drop V L. The compensation process increases the current flowing on the line according to the situation before compensation that proves the series compensation is essential to increase the delivered power.
In all these applications, the voltage drop across the regulator and the quiescent current should be as low as possible while maintaining good output voltage regulation and noise suppression.
