​ High Reliability & Long Lifespan | Shanghai Yongming Showcases Four Major Capacitor Matrices at the 29th CSPES Annual Conference: New Energy Generation & Energy Storage

Shanghai Yongming Electronics will participate in the 29th Academic Annual Conference of the China Power Supply Society (CPSS) from November 6th to 7th, located at Booth D21, Hall B1, of the Suzhou International Expo Center. The company will showcase a comprehensive range of capacitor solutions tailored for five key sectors: new energy power generation and energy storage, electrified transportation, AI servers, robotics and motor drives, and power component peripherals.

In the field of new energy power generation and energy storage, Yongming’s capacitor portfolio covers core applications such as photovoltaic (PV) inverters, power conversion systems (PCS), and battery management systems (BMS). From high-voltage DC-bus support and filtering to stable operation across a wide temperature range under heavy loads, Yongming offers a matrix of highly reliable, long-lifespan capacitor solutions.

PART 01: Yongming Capacitor Solutions for New Energy Power Generation and Energy Storage

1) Inverters: Overcoming Challenges in High-Voltage Filtering and Miniaturization

Inverters are essential for converting DC to AC for grid integration, a process that involves navigating challenges like fluctuating solar irradiance and high-frequency switching spikes. For filtering requirements in micro-inverters (low-voltage side) and the input stages of portable energy storage systems, Yongming’s LKM series of liquid aluminum electrolytic capacitors—featuring a 10,000-hour lifespan at 105°C, low impedance, and high ripple current tolerance—ensures stable and efficient energy conversion.

For high-voltage DC-bus support, the LK series (e.g., 550V 100μF) excels by combining high-voltage capability with low impedance. Furthermore, to address the industry-wide demand for device miniaturization, Yongming offers the VKM series of surface-mount (SMD) liquid capacitors (e.g., 35V 22μF), which provide high capacitance in a compact form factor, effectively resolving the constraints of high-density circuit design.

2) Power Conversion System (PCS): High-Power DC-Link Support and Extreme Thermal Management

During high-power charging and discharging, the DC-link (DC bus) of a Power Conversion System (PCS) is highly susceptible to severe voltage fluctuations. To address the requirements for high-voltage bus filtering and energy buffering, the CW3/CW6 series of snap-in aluminum electrolytic capacitors from Yongming—characterized by high ripple current tolerance and low ESR—are ideally suited for 450V–550V high-voltage platforms. Furthermore, the MDP series of film capacitors, with their high power density and low ESR at high frequencies, effectively meet the demands for high-power, high-frequency filtering and extreme thermal management.

3) Battery Management System (BMS): Automotive-Grade Reliability and Ultra-Long Lifespan

As the "brain" of an energy storage battery system, the BMS must monitor voltage and current 24/7, while contending with high-voltage surges and a wide range of operating temperatures. To meet the stringent reliability requirements for balancing control circuits, Yongming’s VGY series of polymer hybrid surface-mount aluminum electrolytic capacitors was developed. These capacitors comply with automotive-grade standards, withstand high-voltage and high-current surges, and offer exceptional reliability—featuring an ultra-long lifespan of 10,000 hours at 105°C and stable performance across a broad temperature range.

For high-voltage sampling and power supply filtering applications, the LKL series (rated for 125°C with a 5,000-hour lifespan) and the LK series (capable of withstanding high voltages up to 600V) provide flexible, complementary solutions, ensuring the stable operation of the BMS even under extreme conditions.

PART 02: From Millisecond-Level Transient Response to Extreme Temperature Extremes—Yongming’s Wide-Temperature-Range Solutions Empower Your Systems

Energy storage applications present a variety of rigorous challenges: from outdoor inverters enduring long-term exposure to the elements, to power conversion systems (PCS) operating under the intense heat of full-load conditions, and the demanding cold-start requirements for equipment in frigid environments.

Yongming offers a comprehensive capacitor matrix covering the entire energy storage chain—from inverters and PCS units to Battery Management Systems (BMS). Our product portfolio includes the LKM/LK/VKM series (specialized for inverters), the CW3/CW6/MDP/MDR/MAR series (for high-voltage PCS and DC-link film capacitor applications), and the VGY/LKL/LK series (automotive-grade capacitors for BMS).
