6 FAQs about [Requirements for replacing low voltage compensation capacitors]

Should electrolytic capacitors be replaced with MLCCs?

What is a low voltage power capacitor?

The low voltage power capacitors comply with most national and international standards. Other voltages up to 1,000 V are available on request. Capacitor elements made of metallised polypropylene film are self-healing and dry without impregnation liquid. Each capacitor element is individually protected with patented internal fuse protection.

Do MLCC capacitors need a compensation network?

However, to have high performance a more sophisticated compensation network is required, especially when MLCC (Multi Layer Ceramic Capacitor) capacitors are used. MLCC capacitors are widely used at the output of low voltage DC/DC converters because of their low equivalent series resistance (ESR) and low equivalent series inductance (ESL).

Which capacitance should be used in a compensator design?

It should be noted here that the value of the capacitance used in the compensator design must be the small signal value. Ceramic capacitors lose some portion of their capacitance as their biasing voltage increases. The MLCC capacitors which are used in this example have 22μF nominal capacitance.

Why do you need a capacitor in a power factor correction device?

Installing capacitors allows the voltage drops to be reduced upstream of the point where the power factor correction device is connected. It avoids the overload of the network and allows the diminution of harmonics so that no overrating of the installation is necessary.
