Brief description
Fig. 1 is line construction functional schematic of the present invention.
Specific embodiment
For more fully understanding the present invention, to be illustrated below by embodiment.
With reference to Fig. 1 it is illustrated that a kind of bus arrival reminding system of present invention offer, electric including order
The ac-dc converter circuit module connecting, filtering useless band circuit module, orthogonal stream inverter circuit module, output device, described bus arrival reminding system also includes suppressing high frequency electric harmonic wave to produce the electromagnetic filter circuit of pollution to electrical network, in order to improve power factor, reduce harmonic wave, realize the power factor regulating circuit of constant power output, in order to prevent abnormality from producing the protection circuit of infringement to electron tube, described electromagnetic filter is electrically connected between voltage input end and ac-dc converter circuit module, described power factor regulating circuit is connected between ac-dc converter circuit module and filtering useless band circuit module, described protection circuit is arranged among orthogonal stream inverter circuit module.
The electromagnetic filter circuit that the present invention provides, is made up of inductance and electric capacity.
The APFC that the present invention provides.This kind of circuit of power factor correction will use special integrated circuit, transistor and some peripheral cells, because being related to active components and parts referred to as power factor regulating circuit.
The protection circuit that the present invention provides.In normal operation, the voltage that setting auxiliary winding produces on electric capacity C2 only has 20-25V（Or it is more lower）, it is insufficient to allow circuit turn-on.Therefore audion cannot get enough base currents and trigger current, is in cut-off and off state, at this moment abnormal protection circuit is inoperative.And once abnormality, the voltage that C2 induces exceedes the trigger voltage of circuit, makes circuit turn-on, thus turn-on transistor, makes orthogonal stream inverter circuit module from service, and will not trigger again.
