The present invention relates to an inverter circuit which makes its protective function possible and output voltage and luminous intensity adjustable in a neon stabilizer. When the neon stabilizer is not loaded without a neon tube, or it is overloaded, or its output voltage makes a short circuit or it is overheated, it is not made to generate its own output, and it has a remarkable effect on power saving and its life is lengthened due to high dependability. In order to reduce a loss of track and transformer to the maximum, high power factor is made by a high power factor compensation circuit 20. On the other hand, DC voltage is boosted and high frequency waves(oscillating frequency) are removed from the power source input terminal by a line filter circuit 10, and oscillation is made smooth by applying constant voltage from the supplementary power source 30 of control circuit regardless of fluctuations in input power source, and output voltage outputted from the output transformer and luminous intensity are made adjustable by adjusting a change in oscillating frequency and duty and power consumption is made reducible to the maximum by making the stabilizer operable with a protective circuit 70 when it is overloaded, its output is short or it is overheated. <IMAGE> |
