Abstract

The invention discloses a current-limiting type single-phase bridge rectifying circuit. The circuit comprises a first capacitor, a second capacitor, a third capacitor, a fourth capacitor, a fifth capacitor, a sixth capacitor, a first resistor, a second resistor, a third resistor, a fourth resistor, a first diode, a second diode, a third diode, a fourth diode, a fifth diode, a sixth diode, a seventh diode, an eighth diode, a ninth diode, a twelfth diode, a transformer and a current source. According to the current-limiting type single-phase bridge rectifier circuit, the diodes, the capacitors and the peripheral resistors are adopted to form a higher harmonic filter circuit, so higher harmonics generated by the transformer can be effectively filtered at the input end; therefore, the influence of clutter current on a load can be avoided under the condition of not adjusting a load end circuit, the additional burden on a rectifier diode is also avoided, and the service life of a device is prolonged.
