E Series Low Voltage Capacitor Type EPLCR LV capacitors feature the Latest design for power quality solutions, widely used in a variety of applications and make a simple, economical reliable source for reactive power on electric power systems for improving power factor.
The low power factor is not an issue because the capacitive power supply power rating is not high enough for a power factor correction (PFC) to be required. The Standard IEC 61000-3-2 requires PFC for power supplies only with a power output of more than 25 W. 04. CONSTRUCTION OF A CAPACITIVE POWER SUPPLY
One important point to remember about parallel connected capacitor circuits, the total capacitance ( CT ) of any two or more capacitors connected together in parallel will always be GREATER than the value of the largest capacitor in the group as we are adding together values.
Capacitance variation due to operating voltage and temperature must be very low to keep the available load current stable. Capacitance drop during the lifetime of the capacitor must also be kept very low. For most applications with this topology, the input capacitance will be between 100 nF and 1000 nF.
Capacitive power supplies designed for long load life require capacitors with foils and dimensions specifically designed for this application. For its capacitance stability and ruggedness, we recommend using THB film capacitors like the Würth supply applications.
We can also define the total capacitance of the parallel circuit from the total stored coulomb charge using the Q = CV equation for charge on a capacitors plates. The total charge QT stored on all the plates equals the sum of the individual stored charges on each capacitor therefore,
