在线电容系列计算器

在线电容系列计算器是一种工具,用于计算电容器在串联电路中的等效电容值。电容器在串联电路中具有不同的特性,它们的等效电容值取决于它们的电容值、数量和排列方式。在线电容系列计算器通常要求输入电容器的电容值和数量,并可能需要提供其他参数,例如电容器的最大工作电压和频率。根据这些参数,计算器将自动计算出电容器在串联电路中的等效电容值,并显示在屏幕上。电容器在串联电路中的等效电容值可以用于计算电路的共振频率和带宽,这在设计滤波器和其他电路时非常有用。需要注意的是,电容器在实际应用中可能会受到温度、电压和频率等因素的影响,因此在实际电路设计中需要进行充分的测试和验证,以确保电路满足设计要求,并保证电路的可靠性和稳定性。

Calculate the total capacity according to each series capacity.

Capacitance1 Please select units.
Capacitance 2 Please select units.

Equivalent capacity Please select units.
 

1. total electricity = power of series capacitor. QT=Q1=Q2=Q3....
2. the total voltage = the voltage of each series capacitor., E=V1+V2+V3....
3. reciprocal of total capacitance = reciprocal sum of series capacitance.  1 / CT = 1 / C1 + 1 / C2 +………
4. total energy = energy of each series capacitor.,  WT=W1+W2+W3....

Pressure calculation formula:

Total voltage:U
U1=C2*U/(C1+C2)
U2=C1*U/(C1+C2)
Example:C1 is 10UF  C2 is 22UF  The upper formula shows that the voltage at both ends of C1 is 15.62V, and the voltage at both ends of C2 is 34.74V.When the capacitor is connected in series, the voltage and capacitance value are inversely proportional to each other.。

But when one capacitor breaks down due to various reasons, it is not very reliable to add the total voltage to the other capacitor. Therefore, the series of high-voltage capacitors should be treated with caution.

For high voltage circuits, capacitors in series will not be ideal for "automatic" distribution withstand voltage, and must be separately and on hundreds of K_or M_above the voltage divider resistance.
