Generating Electromagnetic Fields Through Pulsed Energy Supply by PPM Pulse Position Modulation Control

摘要

In this paper an experimental model of pulsed electromagnetic fields generation from pulse position modulation PPM voltage in the time domain is developed. Previously a Pulse Width Modulation PWM is required. Due the PWM modulation serves to provide a variable power by digitally controlled and consequently the PPM modulation is a voltage pulse with a constant time duration but variable position in the period T in the time, thus, controlled energy regulation is supplied to the load per unit time. Development work current transient simulations and experimental tests magnetic field strength in two different coils with inductance values. Applications of this research have two reaches; Pulsed electromagnetic fields generation to assist in the treatment of muscle pain in people which is object of this work.
