Abstract
The invention discloses a rectifier filter with a simple circuit. The rectifier filter comprises two rectifier diodes and two filter capacitors, wherein the two filter capacitors are connected in series; the two rectifier diodes are connected in series; the two series-wound rectifier diodes are connected with the two series-wound filter capacitors in parallel; the rectifier filter performs rectifying and filtering on the input alternating current voltage to obtain a smooth direct current voltage, wherein the filter capacitors adopt tantalum electrolytic capacitors; the filter capacitors are smaller in volume under the same voltage resistance and capacitance, so that the volume of the rectifier filter can be reduced; in addition, the rectifier filter is stable in performance and can keep good electrical property after long-term operation; chip resistors for discharging are built in the filter capacitors; after the power supply is cut off, the chip resistors can discharge the electric energy stored in capacitor cores within a quite short time to reduce the voltage of the capacitor cores to be zero, so that bleeder resistors are not required to be connected at the two ends of the filter capacitors in parallel; and therefore, the circuit is simpler.
