Abstract
An inverter controller for controlling a three-phase inverter used for generation and subsequent injection of pulse code signals on power lines in a utility load management system is disclosed. The controller includes read-only-memory devices (208, 210) for generating address bus information, read-only-memory devices (212, 214, 216) for generating gate control signals for inverter main valve SCRs, and read-only-memory devices (236, 238) for generating timing sequence control signals. The controller is responsive to microprocessor initiated control signals and features a state machine design.
