Component Specifications

Definition
Primary and secondary windings are conductive wire coils wound around a magnetic core in transformers and inverters. The primary winding receives input electrical energy, creating a varying magnetic field that induces voltage in the secondary winding, enabling voltage transformation, isolation, or inversion with precise turns ratio control for efficient power conversion.
Working Principle
Operates on electromagnetic induction: alternating current in the primary winding generates a time-varying magnetic field in the core, which induces a proportional voltage in the secondary winding based on the turns ratio (Vp/Vs = Np/Ns), facilitating energy transfer without direct electrical connection.
Materials
High-purity electrolytic copper or aluminum conductors with enamel, paper, or polymer insulation; silicon steel, ferrite, or amorphous alloy cores; epoxy or varnish impregnation for mechanical stability and thermal management.
Technical Parameters
  • Inductance Precise values for specific frequency operation
  • Resistance Low DC resistance to minimize losses
  • Turns Ratio Adjustable based on voltage transformation requirements
  • Voltage Rating Up to 35 kV for industrial applications
  • Current Capacity Designed for load-specific amperage
  • Insulation Class Class A (105°C) to Class H (180°C)
Standards
ISO 9001, IEC 60076, IEEE C57.12.00, DIN EN 61558
