Discover the Power of Film and Electrolytic Capacitors

 

Capacitors play a crucial role in power conversion circuits, providing ride-through energy and reducing ripple and noise. Choosing the right type of capacitor can greatly impact the size, cost, and performance of your system. In this article, we will explore the advantages of film and electrolytic capacitors in various applications.

 

Film Capacitors: Reliable and Efficient

 

When it comes to applications like electric vehicles, renewable energy, and industrial drives, film capacitors shine. With their low Equivalent Series Resistance (ESR), they excel in handling ripple currents and boast high surge voltage ratings and self-healing performance. Film capacitors are ideal for supplying or absorbing large high-frequency ripple currents with utmost reliability and minimal losses. They are also perfect for high DC bus voltage applications, minimizing resistive losses and ensuring optimal performance.

 

Unlike aluminum electrolytic capacitors, which have voltage limitations, film capacitors can withstand higher voltages, making them a cost-effective choice for applications operating at higher voltages. Avoid the hassle of connecting multiple devices in series or adding voltage balancing resistors, which only increase energy loss and BOM cost.

 

Aluminum Electrolytic Capacitors: Energy Storage Powerhouses

 

When energy storage density is the primary concern, aluminum electrolytic capacitors are the go-to option. They are particularly useful in commercial off-line power supplies, where cost-effective bulk energy storage is essential for maintaining DC output voltage during power outages. By appropriately derating these capacitors, issues such as life and reliability can be mitigated.

 

However, it's important to note that aluminum electrolytic capacitors have limitations when it comes to overvoltage. They can only withstand about 20% overvoltage, while film capacitors can handle up to twice the rated voltage for short periods. With their self-healing capability, film capacitors offer a safer response to accidental overpressure, ensuring enhanced safety in practical applications.

 

Wide Range of Applications

 

Whether you're working with UPS systems, power conditioning for wind or solar generators, general-purpose grid-tied inverters, or welding machines, film capacitors are the preferred choice. They excel in matching the power requirements of these systems and offer robustness in the face of transient overvoltages on the DC link.

 

Repairing Power Capacitors

 

At Smiler Electronic Industrial Co., Ltd, we understand the importance of maintaining and repairing power capacitors. While some faults, such as oil leakage on the casing or at the welding seam, can be repaired on-site using tin-lead solder, other issues like insulation breakdown or increased loss tangent value require specialized equipment at our factory.
