The capacitor charging method can be used in Photovoltaic (PV) systems for two typical applications: a very simple and cheap way (1) to trace the I–V curve of a PV generator of whatever size and (2) to track the Maximum Power Point (MPP), especially when the partial shading occurs. ...

These three components form a low-Q series tuned circuit whose impedance versus frequency curve has the characteristic shape of Fig. 3.25, showing a minimum impedance at self-resonance. Sign in to download full-size image Figure 3.25. Capacitor Self-resonance. The term “high frequency” here ...
In a different example, the discharge through a resistor of a capacitor held at a DC potential for a while will be well-modeled by the usual exponential equation during the rapidly-changing portion of the discharge curve. During the “long tail” portion of the curve however, the capacitor w...
Use the preceding equation when the capacitance is defined as the local gradient of the charge-voltage curve for a given voltage: C(v)=dQ(v)dv i=dCdtv+Cdvdt Use the preceding equation when the capacitance is defined as the ratio of the charge Q to the steady-state voltage: C(v)=Q(...
voltage curve of a BST variable capacitor device. The time variant hysteresis effect reduces the maximum capacitance attainable by the variable capacitor and shifts the capacitance vs. voltage curve within the higher capacitance region (i.e., at a low bias voltage) region downward. The magnitude ...
