My contribution is to point out a circuit that suits your title: " A path for capacitor's charging, and another for discharging it ". It is a solution commonly used to drive a N-channel mosfet/IGBT in the configuration high-side (load grounded). This avoids the use of P-channel mosfet, typically showing higher RDSon.
Discharging a capacitor means releasing the stored electrical charge. Let’s look at an example of how a capacitor discharges. We connect a charged capacitor with a capacitance of C farads in series with a resistor of resistance R ohms. We then short-circuit this series combination by closing the switch.
In this article, you will learn about charging and discharging a capacitor. When a voltage is applied on a capacitor it puts a charge in the capacitor. This charge gets accumulated between the metal plates of the capacitor. The accumulation of charge results in a buildup of potential difference across the capacitor plates.
Capacitor Discharge Graph: The capacitor discharge graph shows the exponential decay of voltage and current over time, eventually reaching zero. What is Discharging a Capacitor? Discharging a capacitor means releasing the stored electrical charge. Let’s look at an example of how a capacitor discharges.
This current is in the opposite direction to that on charge. Therefore, it is considered as negative. As time passes, the charge, the internal p.d. across the capacitor and hence its discharge current gradually decreases exponentially from maximum to zero as illustrated in Fig. 1.
For the equation of capacitor discharge, we put in the time constant, and then substitute x for Q, V or I: Where: is charge/pd/current at time t is charge/pd/current at start is capacitance and is the resistance When the time, t, is equal to the time constant the equation for charge becomes:
Charging and discharging capacitors
The discharge of a capacitor is exponential, the rate at which charge decreases is proportional to the amount of charge which is left. Like with radioactive decay and half life, the time constant will be the same for any point on the graph:
