The generic capacitor C has a setting for initial voltage (accessed by clicking on the component), but it doesn''t seem to do anything.

Nevertheless, you can set initial conditions for the node voltages around the cap. See below, from the help. Note that setting ICs can make it harder for LTspice to find the DC operating point:.IC — Set Initial Conditions. The .ic directive allows initial conditions to be specified. Node voltages and inductor currents may be specified.

Power Factor Correction Capacitors. These high-voltage capacitors play a key role in the electricity grid, performing functions that can improve the efficiency, capacity and stability of power supply systems.
In the first hand, I have tried to charge the capacitors in a period of time. However, the charging current is very high and I am not sure whether the capacitor will be completely charged or not. Therefore, I am looking for a way to initiate the initial state of charge of a capacitor in SPICE.
Under these conditions, the peak voltage on C3 is around 2.35V. 2 The bias voltage can be modified and the output voltage will show the resultant percentage change in the capacitance. For example, if the output
So, setting your adjustable voltage supply to 50.75v with a 10k Ohm 1/4W resistor in series and waiting until the voltage across the resistor was less than .75v will ensure that your capacitor is acceptable. Don''t allow the voltage across the resistor to exceed 25v at any point in time.
Based on this article, there are four methods to construct a variable capacitor. The most obvious approach would involve modeling it as a controlled voltage source and incorporating feedback

Let''s say that you want a capacitor that can supply 1 A for 1 minute while having it''s voltage drop from 10 V to 9 V over that time. That would be a 60 farad capacitor. Capacitors that large with sufficiently low series resistance are not going to come your way cheaply.

Apply DC voltage: Hook up a DC voltage source to the circuit comprising the capacitor and resistor. Start timing: As soon as you apply the DC voltage to the circuit, start a timer. This marks the beginning of the charging process for the
How do you determine the appropriate voltage rating for a capacitor in a circuit? To determine the correct voltage rating for a capacitor, the working voltage of the circuit must be considered. A common rule of thumb is to select a capacitor with a voltage rating that is at least 1.5 times higher than the circuit''s maximum voltage.

Based on this article, there are four methods to construct a variable capacitor. The most obvious approach would involve modeling it as a controlled voltage source and incorporating feedback to ensure the source aligns with the capacitor equation: So let's do that!
When selecting capacitors for an embedded system, consider the following parameters: The working voltage of a capacitor should be 20% higher than the working voltage of the circuit. For an AC circuit, ensure the capacitor has no polarity. For precise circuit performance, the tolerance of the capacitor is an important factor.
The voltage is more important. Start capacitors should be ~1.5 times the line voltage of the motor. I'm assuming your motor is running on 115-120 volts so the 250V rating is fine. Not all motor capacitor makers use a standard voltage for some reason. But as long as the voltage is as least 1.5 times more your alright.
Now the variable capacitor is complete and is also wrapped in a subcircuit. You can load that subcircuit in a schematic by Navigating to “Subcircuit” and then “Load Subcircuit”. The mathematical expression that governs its operation is implemented using PSIM source and math blocks. To verify its operation the following circuit can be applied:
Now the voltage of this source needs to be set as integral (I/C). This can be done by utilizing a unit value capacitor along with a (current-controlled) current source, according to Method 2 of the aforementioned article. With this method, the requested integral is just the voltage across the unit value capacitor.
