The growing demand for renewable energy is expected to drive the expansion of the high-voltage capacitor market in the coming years. Renewable energy, often called “clean” or “green” energy, is derived from naturally replenishable resources that are not depleted when used. High-voltage capacitors play a crucial role in renewable energy systems by enabling energy storage, regulating voltage levels, improving power factor, and providing transient voltage protection. For example, in July 2024, the U.S. Energy Information Administration (EIA), a federal statistical agency, reported that renewable energy consumption in the United States rose by 2% from 2022, reaching a record 8.2 quads in 2023. Consequently, the increasing adoption of renewable energy is fueling growth in the high-voltage capacitor market.

Leading companies in the high-voltage capacitor market are focusing on innovative solutions, such as high-voltage supercapacitor modules, to enhance energy storage and voltage stabilization in renewable and industrial applications. These supercapacitor modules combine multiple electrochemical capacitor cells in series, delivering high power density, rapid charge-discharge capability, and extended cycle life compared to traditional electrolytic capacitors. For example, in July 2023, Nippon Chemi-Con Corporation, a Japan-based capacitor manufacturer, launched a Supercapacitor Module for Large-Scale Equipment designed for systems up to 800 V. The module features 24 series-connected cells (2.8 V, 3150 F each), integrated voltage-balancing circuitry and thermal sensors for improved reliability, and a 19-inch rack-mountable design for easy installation. It provides superior power buffering, voltage-drop compensation, and peak-assist performance for renewable energy generation and industrial machinery stabilization.

In September 2023, Knowles Corporation, a U.S.-based provider of high-performance components and precision devices including ceramic capacitors, RF filters, and specialty electronic solutions, acquired Cornell Dubilier Electronics for $263 million.

High voltage capacitors are essential components for storing charge and energy in applications requiring high voltage. These capacitors, characterized by a cylindrical shape with a flat cover or semi-spherical envelope, a sealing element, and additional accessories, are crucial in large pulse power systems for tasks like pulse shaping or peaking. They are particularly valued for their low-loss and lightweight properties, often immersed in oil for optimal performance.

The primary categories of high voltage capacitors encompass high voltage plastic film capacitors, high voltage aluminum electrolytic capacitors, high voltage ceramic capacitors, and other variants. High voltage plastic film capacitors leverage a thin plastic film as the dielectric, making them suitable for high-frequency, high-power applications, as well as pulsed power energy discharge scenarios. Capacities of high voltage capacitors are classified into ranges such as 500-1000V, 1001-7000V, 7001-14000V, and above 14000V.
