Capacitors for power electronics

Product catalog summary
General Overview
ZEZ SILKO specializes in manufacturing polypropylene film capacitors for power electronics, offering advanced technology and high-quality materials. These capacitors are used in frequency converters and inverters for traction drives, wind, and solar power systems, providing a modern alternative to traditional electrolytic capacitors.
Lifetime
The lifespan of capacitors is influenced by hotspot temperature, current, and voltage, with a typical service life ranging from 100,000 to 200,000 hours, depending on the type and conditions.
Definitions and Safety
Key terms include rated capacitance, rated voltage, RMS voltage, and peak voltages. Capacitors must operate within specified conditions to ensure safety and prevent risks such as explosion or fire, with a fire load of approximately 40MJ/kg.
DC Link Capacitors
Designed for DC supplies, these capacitors protect networks from voltage spikes and filter AC ripple. They feature self-healing, dry-type construction with metallized PP film, enclosed in an aluminum case with environmentally friendly materials. Installation can be in any position, but excess temperatures can reduce lifespan.
Technical Specifications
Capacitors are available in various types with different rated voltages, capacitances, and dimensions, complying with IEC 61071 and EN 61881 standards. Specific parameters such as maximum current, peak voltages, and inductance are detailed in accompanying tables.
Installation Instructions
Capacitors should be mounted using specified torque values to ensure longevity and performance. They can be installed in any orientation, and additional parameters can be customized upon request.
Specifications
Capacitors operate within a temperature range of -40 to +85°C, with a maximum hotspot temperature of 85°C and a service life of 120,000 hours under specified conditions.
Procedures
Installation instructions specify mounting positions and maximum torque values for connection cables and terminals. Capacitors should be mounted vertically, and flexible connection cables must allow for movement to ensure proper function of overpressure disconnectors.
Standards and Norms
Capacitors comply with IEC 61071 and EN 61881 standards, with specified voltage tests to ensure safety and reliability.
Recommendations
For AC filter capacitors, use in AC/DC power converters and inverters is recommended. The construction ensures low stray inductance and high reliability, with self-healing technology and overpressure disconnectors for safe operation.
Technical Data and Limit Values
Detailed tables provide technical data for capacitors, including rated voltage, capacitance, current, peak voltage, and dimensions, along with dimensional drawings for reference.
Applications
Damping snubber capacitors protect semiconductors, specifically IGBT transistors, designed to withstand heavy conditions with low self-inductance and resistance.
Commutating Capacitors (Spare Parts)
Available in various types and specifications, with options to order other capacities and voltages upon request.
