Power Capacitor

Power Capacitor

Our Power Capacitor is a filtering and support capacitor specially designed for high-power-density power electronic equipment. It is a core energy storage component in high-power converters, inverters, and rectifiers. This product uses an optimized low equivalent series inductance and low equivalent series resistance structure. It exhibits extremely low heat generation and excellent filtering effects under high-voltage, high-current, high-frequency conditions. The internal structure uses multiple parallel low-inductance connections. This effectively reduces impedance at high frequencies, ensuring good absorption and filtering of high-frequency ripple currents. Our product has wide applications in wind power converters, photovoltaic inverters, high-power frequency converters, and energy storage converters.

Advanced Thermal Management

 

In thermal management, our Power Capacitor has been carefully designed. The internal structure uses low-thermal-resistance heat paths and optimized heat dissipation structures. Heat generated inside the capacitor is quickly conducted to the housing and dissipated to the surrounding environment. Each product undergoes full-load temperature rise verification before shipping. This ensures core temperature rise remains within the safe range under the most severe operating conditions. Our product also has a built-in overvoltage isolation device. In the event of DC bus overvoltage, it can safely isolate the capacitor from the circuit to prevent fault expansion. With excellent electrical performance and reliable safety protection, our product has become the preferred choice for many power electronics equipment manufacturers.
