The PEC series capacitors are core components of power electronic devices (such as frequency converters, inverters, rectifiers, SVG/APF, etc.), specifically designed for high-frequency, high-ripple, and fast-switching power electronic conversion scenarios.

These capacitors undertake key functions such as energy storage, filtering, voltage stabilization, and reactive power compensation, and are the foundation for achieving power conversion and control. Its applications cover core fields such as industrial transmission, new energy power generation, power grid transformation, and rail transit.
