Kesheng AC filter capacitors designed for reliability

Kesheng AC filter capacitors are excellent solutions to filter high ripple harmonic content in the input of AC/DC converter, and output of the DC/AC inverter systems.  They are widely applied in Inverter Systems, Motor Drives,Battery Chargers, AC and Harmonic Filtering, Clamping / Damping Systems, Power Factor Correction (PFC).

Key Requirements

Since a portion of these capacitors has the capacity to handle substantial energy levels, and multiple units can be linked in clusters, ensuring safety is of paramount importance for this technology. To meet this imperative, the capacitors must exhibit exceptional dependability while integrating cutting-edge safety disconnection mechanisms to safeguard against potential disastrous breakdowns.

The role of AC filter capacitors

1) Reduce the pulsation component. The rectified current is a unidirectional pulsating current, not a smooth DC current. The function of the capacitor is to use its charge and discharge characteristics. Here, high charge and low discharge flatten the unidirectional pulse wave while also increasing the output. The average value of DC voltage. (peak value at no load)
2) The remaining AC components in the circuit filter out high-order harmonics. Due to the direct connection of the capacitors, these stray elements are shorted and recirculated. In order to compensate the inductive impedance effect of the large-capacity capacitor, a small-capacity capacitor can be connected to the large capacitor to form a high-frequency circuit.
3) Improve the instantaneous overload capability of the power output. The power supply filter capacitors are all large-capacity, and their energy storage function can improve the instantaneous current characteristics of the circuit to adapt to those loads with excessive transient currents.
