Topic:Kingtronics Typical Application For High Capacitance And High Voltage MLCC
Content:
A typical application for high capacitance, high voltage capacitors is a bulk filter capacitor shown in Figure 1 in a bipolar transistor totem pole configuration high voltage, high capacitance MLCCs are commonly used as input capacitor filters.To obtain the required capacitance and high voltage rating the MLCCs are often placed in parallel or stacked vertically. This requires careful soldering and attachment processing, due to the larger case sizes required for the application. The basic function of the input capacitor filter is to hold up the rectified power bus line voltage as well as for filtering common mode noise.Common mode noise flows asymmetrically through both input lines. The current into the load is supplied by the input filter capacitor bank rather than from the power supply, until the point at which the input voltage again equals the voltage across the filter capacitor, see wave forms in Figure 2.
