H-BRIDGE INVERTER SYSTEM USING SERIAL COMMUNICATION

摘要

PURPOSE: An H-bridge inverter system is provided to simplify the signal line between the master controller and cell controller by adopting a serial communication system between the master controller and cell controller. CONSTITUTION: An H-bridge inverter system comprises a master controller(10) having a controller(12) for controlling an acceleration and transmission of a motor, and which calculates voltage/current values for the acceleration and transmission; a cell controller(20) arranged in each of power cells, and which performs a PWM voltage control and a phase control in accordance with the control signal output from the master controller, and performs operations of gating signal generation and cell monitoring and protection; and a connection unit(30) for performing a data communication between the master controller and the cell controller through a serial communication system.
