Description
Technical field
The utility model relates to plant light compensation electric ballast industry, and a kind of full-bridge low-frequency square-wave ballast arc ignition circuit without auxiliary winding, is applied to the striking of full-bridge low-frequency square-wave circuit ballast specifically.
Background technology
The mode of current low-frequency square-wave full-bridge circuit ballast many employings pulse striking carries out lighting, and striking inductance needs an extra increase auxiliary winding, also will have pulse arc ignition circuit, circuit can be made to become complicated, increase ballast volume.
Summary of the invention
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art, a kind of full-bridge low-frequency square-wave ballast arc ignition circuit without auxiliary winding is provided, the utility model solves the technical scheme that its technical problem adopts: structure of the present utility model comprises AC power supply module, current rectifying and wave filtering circuit module, APFC booster circuit module, BUCK reduction voltage circuit module, drive and control circuit module, full-bridge is held concurrently arc ignition circuit module, it is characterized in that AC power supply module and current rectifying and wave filtering circuit model calling, current rectifying and wave filtering circuit module and APFC booster circuit model calling, APFC booster circuit module and BUCK reduction voltage circuit model calling, BUCK reduction voltage circuit module and driving and control circuit model calling, to drive and control circuit module and full-bridge arc ignition circuit of holding concurrently is connected, full-bridge hold concurrently arc ignition circuit also with BUCK reduction voltage circuit model calling, by to drive and control circuit module control BUCK reduction voltage circuit module and full-bridge are held concurrently the normal operation of arc ignition circuit module, full-bridge is held concurrently in arc ignition circuit module and is provided with four MOSFET metal-oxide half field effect transistors, full-bridge arc ignition circuit module of holding concurrently adopts in low-frequency square-wave with the striking mode of high-frequency signal and without auxiliary winding.
Operation principle: after AC power enters ballast, the direct current of pulsation is become through current rectifying and wave filtering circuit, the smooth direct current of 400V is become again through APFC booster circuit, make the power factor of ballast reach more than 0.95 simultaneously, then enter BUCK reduction voltage circuit and reduce to suitable voltage, finally access full-bridge circuit, BUCK reduction voltage circuit and full-bridge circuit control by driving and control circuit, four MOSFET in full-bridge circuit are all operated in low-frequency square-wave state, the high-frequency square-wave signal in several cycle is there is in the rise/fall of each low-frequency square-wave along place when lamp is not lighted, the frequency of this square-wave signal and the LC series resonance peak of ballast are close, therefore the electric capacity generation resonance that is together in series with C102 of inductance L 101 and C101, because resonance frequency is close to resonance peak, now inductance and electric capacity can produce the voltage of several kilovolts, this voltage can be lighted lamp, once after lamp lights, high-frequency signal disappears, ballast is operated in low-frequency square-wave state.
The beneficial effects of the utility model are, the utility model circuit eliminates the striking auxiliary winding of inductance, simplifies circuit, no matter are that inductance is processed or welding all reduces workload, can also reduce the volume of ballast simultaneously.
