The Roles and Rules of Capacitors
Capacitors are key building blocks of circuits and are found in almost every aspect of circuit design.

6 FAQs about [Capacitor Charging Circuit Design]
Can a capacitor be charged instant?
The charging of a capacitor is not instant as capacitors have i-v characteristics which depend on time and if a circuit contains both a resistor (R) and a capacitor (C) it will form an RC charging circuit with characteristics that change exponentially over time.
How to charge a capacitor?
Once you know the polarity and if you are curious to charge it, you can even use a RPS set it to 5.5V (or 4.95V for safety) and then connect the positive lead of RPS to positive pin and negative lead to negative pin and you should see the capacitor being charged.
How do you charge a super capacitor?
Most super capacitors (supercaps) can be discharged down to 0 V and recharged to their maximum voltage with the manufacturer recommended charge current. A simple voltage regulating LED driver with constant current, usually regulated by sensing a low side, series current sense resistor, then a voltage clamp can be used to charge a super capacitor.
Why does a super capacitor charge at a constant voltage?
Eventually, the super capacitor voltage, and therefore the charging circuit’s operating efficiency, increases so the capacitor charges at the desired constant (fast or max) charge current, ICHG, until it reaches and remains at constant voltage (CV) regulation voltage, VREG.
How to choose a switched-capacitor Charger?
The most important decision for a switched-capacitor charger is selection of the CFLY capacitor. A minimum of two CFLY capacitors are required per phase, with four being optimal. Additional CFLY capacitors can be used, but returns are diminished by added cost and board space.
How long does a capacitor take to charge and discharge?
This charging (storage) and discharging (release) of a capacitors energy is never instant but takes a certain amount of time to occur with the time taken for the capacitor to charge or discharge to within a certain percentage of its maximum supply value being known as its Time Constant ( τ ).
