  1. A TECHNICAL SEMINAR Presented by VED PRAKASH NAYAK EE200118008 Under the guidance of Mr. SHYAMALENDU MOHANTY

  2. INTRODUCTION • Geometry of construction • Equivalent ckt. of capacitor

  3. BASIC PROPERTIES • Electrical • Capacitance of capacitor • Dissipation factor • measure losses

  4. BASIC PROPERTIES • Temperature effect • Various transformation • at different temp.

  5. BASIC PROPERTIES • Voltage effects • Effect of voltage • Voltage coefficient of • capacitance

  6. BASIC PROPERTIES Frequency effects Varies with different dielectric Aging What is aging Aging cycle

  7. DISCUSSION AND RESULTS • Electrical characteristics of HTPC • Impedance vs. Frequency • Capacitance vs. Frequency • Phase angle vs. Frequency

  8. CAPACITOR PERFORMANCE • Frequency • Voltage Range

  9. CAPACITOR PERFORMANCE • Energy Density • Temperature Coefficient • Specific Power Density

  10. CAPACITOR PERFORMANCE • High Power Testing • Step to DevelopHTPC

  11. FEATURES • Improved Mechanical Constructions • Enhanced impregnation and oil circulation • Improved transient over voltage endurance • High inrush & discharge current withstanding capability

  12. FEATURES • Low Dielectric Loss • Corona ring design • Insulator Bushings

  13. APPLICATIONS • Automotive applications • Industrial application • Live-Line Indication • Electrostatic Spray Guns • DC Power Supplies

  14. CONCLUSION • Connections should be solid and large in proportion to the termination area • Capacitor electrical performance is similar to that of tantalum electrolytic capacitor • Finds applications in military, avionics, and wireless communications
