Film capacitors have high insulation impedance, excellent frequency characteristics, and low dielectric losses. Because of these advantages film capacitors are widely used in analog circuits. It is necessary to use capacitors with good frequency characteristics and low dielectric loss in the signal cross-connection part to ensure that the signal is transmitted without too much distortion. There are many roles of film capacitors, and in this article, I would like to discuss the role of film capacitors in reducing impedance and suppressing electromagnetic interference in power supplies. What is the role they present in the circuit?
Suppression of power supply electromagnetic interference.
　　Application in power electronic circuits. Film capacitors are used in this area, mainly as a buffer for power currents and clamping, resonant bypass and suppression of power supply electromagnetic interference, etc.
　　Impedance reduction.
　　When the film capacitor is used as a bypass, it mainly serves to reduce the impedance of the DC bus and absorb the ripple current from the load, thus effectively suppressing the fluctuation of the DC bus voltage due to sudden changes in the load. When the device is used in resonant converter, it can achieve the resonance function together with inductor.
