Learn MoreThe capacitance of a capacitor can be defined as the ratio of the amount of maximum charge (Q) that a capacitor can store to the applied voltage (V). V = C Q. Q = C V. So the amount of charge on a capacitor can be determined using the above-mentioned formula. Capacitors charges in a predictable way, and it takes time for the capacitor to charge.

Learn MoreAll voltage regulators want a peaceful life; if there is an output capacitor then any fast cyclic changes in load current are largely dealt with by that capacitor and the lazy output from the regulator is only expected to deal with topping up the charge to the capacitor so that the capacitor can handle the next cycle of load current change.
Learn MoreLet we calculate the required reactive power in kVAR or capacitor bank to be connected across the motor? Here, PF 1 = 0.7. PF 2 = 0.96. Required capacitor bank = 100 x tan (cos-1 (0.7)- cos-1 (0.96)) = 72.85 kVAR. Hence you can connect three 25kVAR capacitor bank across the panel for improving the power factor from 0.7 to 0.96

Learn MoreCapacitors react against changes in voltage by supplying or drawing current in the direction necessary to oppose the change. When a capacitor is faced with an increasing voltage, it acts as a load: drawing current as it stores energy (current going in the positive side and out the negative side, like a resistor).
Learn MoreThe charge to replenish the bootstrap capacitor must come from some larger bypass capacitor, usually the VDD bypass capacitor. As a rule of thumb, this bypass capacitor should be sized to be at least 10 times larger than the bootstrap capacitor so that it is not completely drained during the charging time of the bootstrap capacitor.
