Abstract: The present invention provides an inverter circuit with a power factor corrector. A power source provides a power signal of alternating current. An electromagnetic interference filtering unit and a rectifier unit receive the power signal of alternating current, filter and rectify the power signals, and then output a half-wave power signal of direct current. A voltage adjusting unit provides a voltage adjusting value. A power factor corrector receives the half-wave power signal of direct current, connected to the voltage adjusting unit, converting the voltage of the half-wave power signal of direct current in accordance with the voltage adjusting value, and then outputting a power signal. An inverter steps up the voltage and outputting a power signal with high voltage to a load which is subsequently connected to the inverter, such that the power signal with high voltage has preferred corrected power factor and adjusts the brightness of the load.

Abstract: The present invention is a lamp current control circuit applied to a high voltage outputting combination for providing uniformity of lamp current of at least one load. Voltage dividing units of the lamp current control circuit receive high power signals output by the high voltage outputting combination and redistributes high power signals to lower power signals. A signal-processing unit receives the lower power signals distributed by the voltage-dividing units, compares the lower power signals with each other, and outputs the compensation power signal to the control unit. The compensation power signal is compared with a reference power signal of a variable unit, and a comparison power signal is output, thereby uniformly distributing the lamp current inside the load. For the above reason, it prevents power loss inside the load or damage to the load from abnormal lamp currents.

The previous design of transforming low voltage to high voltage through a voltage boosting unit (inverter) is changed to transforming to medium voltage through the rectification unit then is transformed to high voltage through the voltage boosting unit. Therefore loss on the low voltage power supply is eliminated, and performance may increase from 64% to about 80% or more. Thus the low voltage power supply module that otherwise should have extra power and greater watts may be shrunk and power supply efficiency may increase.
