Master-slave control arrangement for power inverter, has slave-control boards comprising driving units that are controlled synchronously by signals for controlling current of transformer units and for changing current into output voltage

摘要

The arrangement has a master-control board with a main-control board that outputs two frequency signals, and slave control boards corresponding to discharge lamps. The slave boards are provided with driving units (21,31) and transformer units (22,32). The driving units are controlled synchronously by the frequency signals for controlling the input current of the transformer units and for changing the current into the output voltage.
