Improvements of Power Supply Systems in Machine to Machine Modules and Fixed Cellular Terminals with Discontinuous Current Consumption

Abstract

The present paper introduces a power supply system for Machine to Machine Modules and Fixed Cellular Terminals with discontinuous current consumption. The architecture proposed tries to solve the input high current peaks derived from the discontinuous current consumption of the PA. The final solution decreases the voltage supply ripple and current peak applied to the battery. The document also describes the problem and shows a practical implementation of the solution proposed.
