Patent ID: 7067989

Claim:
A modularized inverter control circuit packaged and disposed on a printed circuit board and used to connect and control an inverter circuit for driving actions of several lamps, said modularized inverter control circuit comprising: a push-pull type control IC used to output two control signals via two output signal pins NOUT 1 and NOUT 2 , the output signal pins NOUT 1 and NOUT 2 being coupled to any one of a push-pull inverter, a full-bridge inverter, and a half-bridge inverter; a lamp current feedback unit connected to said control IC and said lamps and used to get working currents of said lamps and convert them into voltage forms sent to said control IC; a turn-on voltage limit unit connected to said control IC and said lamps and used to get working voltages of said lamps and send them to said control IC; a brightness adjustment control unit connected to said control IC and said lamps and used to adjust the brightness of said lamps; a lamp protection unit connected to said control IC and said lamps and used for open-circuit and short-circuit protection of said lamps; a power source control unit connected to said control IC and used to provide the required electric power for said control IC; and a reference unit connected to said control IC and composed of several resistors and capacitors and used to provide the required reference values for operation of said control IC.
