Capacitors regulation improvement

Another important application of capacitors is to improve the oltage regiiltition of a power supply systetn. The regulation of a power system at the receiving end is defined bv...

The input capacitor (usually on the order of 0.1-/uF disc or a l-/uF solid tantalum) is required if the regulator is more than 4 in. from the power supply filter, and the output capacitor is generally used to improve transient response performance,... 

Current mode control In this method, as shown in Fig. 10.79, a second inner control loop compares the peak inductor current with the control voltage, which provides improved open-loop line regulation. All of the problems of the direct duty cycle control method (1) and (2) are corrected with this method. An additional advantage of this method is that the two pole second-order filter is reduced to a single pole (the filter capacitor) first-order filter resulting in simpler compensation networks. There are several current mode control ICs available in the market.
