Self-healing polypropylene film technology and dielectric construction

API Capacitors power film capacitors utilize high-isotactic metallised polypropylene dielectric film characterized by ultra-low structural defect density.

When localized electrical flashover occurs under transient overvoltages, the ultra-thin metallization surrounding the weakness point vaporizes within microseconds without producing an electrical short circuit.

This self-healing process halts avalanche degradation of the element and maintains uninterrupted inverter operation. Hermetic metallic or polymer enclosures filled with environmentally safe fluid or polyurethane dry resin transfer heat away from interior wound sections.

Snubber capacitors for switching spike suppression across IGBT modules

Across pulse-width modulated frequency inverters and traction converters, API Capacitors snubber units mount directly onto terminals of IGBT modules, GTO switches, and IGCT thyristors.

Featuring low parasitic inductance and solid copper conductor tabs, the snubber assemblies absorb reactive electrical energy released during rapid semiconductor turn-off events. This limits voltage rise rates dV/dt to safe operational thresholds and prevents thermal breakdown in silicon crystals.

Planar contact tabs provide uniform electrical mating with busbars without introducing mechanical stress.

DC link capacitors for traction drives and renewable energy converters

Intermediate DC links in variable frequency motor drives, wind turbine inverters, and traction converter systems withstand sustained ripple currents at elevated frequencies.

API Capacitors DC range capacitors exhibit low equivalent series resistance ESR, mitigating internal ohmic dissipation under high root-mean-square current loads. Automatic precision edge-controlled winding machines ensure uniform dielectric field distribution across elements.

This preserves rated capacitance and loss factor stability throughout the operating life of industrial equipment.

AC power capacitors for harmonic filtering and grid power conditioning

Power factor correction assemblies and passive harmonic filter banks require resilience against harmonic current distortion.
