Improved Load Current Capability for Cap-Drop Off-Line Power Supply for E-Meter

Texas Instruments

Published Date: 10/27/2011

Description

Standard electronic electricity meters (e-meters) have traditionally used a capacitive-drop power supply (capdrop) plus linear regulator topology to provide a cost-effective power supply. Today opposing forces such as an increase in load currents due to more complex AMR and AMI ommunications circuitry and tighter power consumption regulations force e-meter designers to limit consumption to belo
