Guide to Using Water cooled Capacitors

1. Choosing the Best Capacitor for Your Needs

When choosing a capacitor for an application, select a capacitor with maximum rated voltage RMS, current and reactive power that most closely matches the highest operating voltage and frequency of the application. Take into account any ripple and any DV bias that can occur during operation, as even momentarily over voltage damages the capacitor and reduces its life time. The maximum ratings appear clearly on the data sheet of each capacitor.

The reactive power formula is:

Qc= V2rms x C x 2πf x 10-6

where

Qc is reactive power in kVAr

Vrms is RMS voltage in volts

C is capacitance in µF

f is frequency in kHz

2. Proper Cooling and Termination for Power Capacitors

conduction-cooled power capacitors handle a large amount of power in relatively small volume. In order to operate correctly, capacitors must be terminated properly to ensure uniform cooling of all internal elements.

Four critical requirements must be addressed when using conduction cooled capacitors:

1. Cooling. The entire area of the capacitor’s contacts surface must be placed in contact with the heat sink using a thermal conductive paste to ensure optimal heat conductance. This is particularly critical when the capacitor is working at its maximum limits. Never tighten the bolts beyond the maximum allowed torque.

2. Conduction losses. Most power capacitors are able to supply hundreds of amperes. When several capacitors are connected to a common collector, insufficient collectors’ surface area may result, due to the skin effect, in extreme heating of the bus bar where the current is collected, and overheating of the capacitor despite proper cooling.

3. Induction heating of capacitors. When several conduction-cooled capacitors are assembled between two bus bars, those located closest to the output terminals may experience induction heating. This situation should be avoided by mounting the capacitors as illustrated in diagram B or by building a low inductance path between the bus bars as illustrated in diagram C. The C-Cap technology overcomes this deficiency.
