摘要：PURPOSE: A power saving electronic stabilizer circuit is provided to remove and filter harmonic elements by using a power filter, output a DC static voltage by performing a switching operation, and turn on or off a lamp by using a high efficient RF voltage. CONSTITUTION: A first filter(10) is used for removing noise of input power such as EMI or RFI. An electric wave rectifier(20) is used for rectifying an output of the first filter(10). A first switching portion(30) outputs a DC constant voltage according to a first PWM signal. A control and gate logic portion(33) controls operations of transistors. A variable voltage portion(38) controls an output of the first PWM signal of the control and gate logic portion(33). A second switching portion(50) turns on or off a lamp by filtering harmonic elements. A voltage and current sensor(60) is used for sensing over-current and over-voltage. An abnormal cutoff portion(36) cuts off a stabilizer according to a state of over-current or over-voltage. A brightness sensor(63) is used for controlling the brightness of the lamp. A mobile sensor(61), an amplification and decision portion(62), and a timer and relay driving portion(64) save unnecessary power. A second filter(70) is used for filtering harmonic elements. A current distributor(80) is used for sensing operating current of the stabilizer.
