Capacitor charge and discharge periods is usually calculated through an RC constant called tau, expressed as the product of R and C, where C is the capacitance and R is the resistance parameter that may be in series or parallel with the capacitor C. It may be expressed as shown below: τ...
A current generator (3) charges an electrode (1) linearly in time, and a timer (5) and a discharge circuit (4) discharge the electrode (1). A resistor (6) in series with a capacitor (7) are connected in parallel with the electrode (1) and the discharge circuit (4). The time ...
An RC circuit works by using a resistor to limit the flow of current and a capacitor to store electrical energy. When a voltage is applied to the circuit, the capacitor charges up and then discharges through the resistor, creating a current flow. ...
Discharging a Capacitor Through a Resistor In the following circuit, when the switch moves from the battery + to ground, the voltage across the capacitor is vc(t) = Vse-t/RC Vs vc - EGR 101
采用常规的人体模型(Human Body Model, HBM)进行静电释放(Electro-Static Discharge, ESD)测试时往往容易受到寄生参数的影响,使得电源芯片抗静电能力测量值与实际抗静电能力存在偏差,导致劣质产品通过HBM ESD测试,影响电源芯片产品良品率的提升。为此,提出了一种RC-HBM模型,通过引入RC并联支路,校正因寄生参数引起的静电...
a UNIVERSAL TIME CONSTANT CHART (fig. 3-12) can be used to find the time constant of the circuit. Curve A is a plot of both capacitor voltage during charge and inductor current during growth. Curve B is a plot of both capacitor voltage during discharge and inductor current during decay....
inferior products passing the HBM ESD test. This affects the improvement of the yield rate of power chip products. To this end, an improved HBM model is proposed, one which corrects the deviation of the electrostatic discharge current caused by parasitic parameters by introducing an RC parallel ...

A very common one is trying to charge a 6S LiPo (25.2V fully charged), while using a power supply that is outputting 12VDC. I think you can already recognize the limitation here. You can't get something for free, and when the charger's DC-DC boost converter circuit has to essentially...
To limit the slope of the reapplied voltage and ensure the right triac turn-off, designers usually used a snubber circuit connected in parallel with the triac. This circuit can also be used to improve triac immunity to fast transient voltages. The subject of this paper is, first of all, ...
