Application Scenario

Fast charging pile (DC charging pile): Suppresses voltage fluctuations during high-power charging.
Hybrid Electric Vehicle (HEV): DC link energy storage for energy recovery system.
Hydrogen Fuel Cell Vehicles (HFCVs): Supporting energy buffering between the fuel cell and the drive system.
Inverters and Servo Drives: Absorb voltage spikes generated by IGBT switching and protect power devices.
Uninterruptible Power Supply (UPS): stabilizes the DC bus and ensures smooth switching of emergency power supply.

FAQ

Q: What are the key parameters for industrial motor drives?

A: High withstand voltage (e.g. above 1000VDC), low ESR, pulse current resistance.

Q: How to select the model according to the circuit demand?

A: Define voltage, capacity, frequency, temperature and size limitations, then match material characteristics.

Q: How to select capacitors for high humidity environment?

A: Choose moisture-proof package (e.g. epoxy resin potting) or moisture-resistant material (e.g. PPS).

Q: How to select capacitors for scenes that need to withstand high-frequency pulses?

A: Give preference to metallized polypropylene capacitors to support high dv/dt and pulse current.
