SYNOPSIS

PARAMETERS

INPUT PARAMETERS

• N : Number of turns
• len : length of the coil (meters)
• fill : ratio of coil length to closewound length
• AWG : wire size (American Wire Gauge)
• rho : resistivity of wire (ohm-m)
• dia : inside diameter of coil (meters)
• freq : analysis frequency (Hertz)
• flag : used to calculate coil length.
  • flag=0 : the length given by len is used.
  • flag=1 : the length is calculated from the wire size, number of turns and fill input.

OUTPUT VALUES

• L : calculated inductance (Henries)
• Q : calculated quality factor
• SRF : calculated self resonant frequency (Hertz)
• len_out : length used for the analysis (meters)
• fill_out : fill used for the analysis
• lmax : maximum (closewound) inductance

DESCRIPTION

Function to analyze the electrical characteristics of a single layer, uniformly spaced, air core, solenoid inductor. The physical dimensions of the coil are given as inputs and the inductance, quality factor, and self resonant frequency are calculated.
