Abstract
The utility model provides an electronic ballast with high performance, which is composed of a printed circuit board and a semiconductor device. Because the utility model adopts a novel circuit, the utility model has the advantages of high power factor, low wave crest ratio, low harmonic content, preheating glow starting and abnormal protection, and the service life of a fluorescent lamp can be extended.
Description
The utility model relates to a kind of high-performance electronic ballast.
Existing all kinds of electric ballast mostly adopts bridge rectifier at present, directly use capacitor filtering, alternating current 220V through reaching after the rectification about 320V, is dropped to the following fluorescent lamp of supplying with of 100V again, make energy loss more, and power factor is low has caused very big power loss to electrical network, also have to adopt by the flow pattern electric ballast and improve power factor, but index crest ratio is big, harmonic wave is big, the fluorescent tube life-span is reduced, do not reach the index of national regulation.
The purpose of this utility model provides two kinds of high-performance electronic ballasts of being made up of semiconductor device, the defective that the power factor of having improved electric ballast in the past is low, the crest ratio is high, do not reach the index of national regulation.
The purpose of this utility model is achieved in that a high-performance electronic ballast of being made up of semiconductor device, it is characterized in that: import an end by alternating current 220V and connect resistance (R0), resistance (R0) other end connects electric capacity (C0) upper end and inductance (L1) winding head end, inductance (L1) winding tail end connects electric bridge (D1) ac input end, inductance (L1) second winding one end connects electric capacity (C0), inductance (L1) the second winding other end connects the other end of the ac input end of electric bridge (D1), the anode of the dc output end of electric bridge (D1) connects electric capacity (C1), electric capacity (C9), diode (D12) anode, the other end that diode (D12) negative terminal connects electric capacity (C9) is the A end, the positive supply of power supply sub-ballast, electric bridge (D1) direct current output negative terminal connects electric capacity (C2), electric capacity (C10), diode (D13) negative terminal, the anode that electric capacity (C10) other end connects diode (D13) is the B end, power supply sub-ballast negative supply, the other end of electric capacity (C1) and electric capacity (C2) link together and are fluorescent tube cathode return circuit in the C end power supply sub-ballast.
The purpose of this utility model also is achieved in that high-performance electronic ballast, a kind ofly is connected electric bridge (D1) anode respectively and electric bridge (D1) negative terminal is formed the electric ballast loop by electric capacity (C1) and electric capacity (C2).
The high-performance electronic ballast that the utility model provides; owing to adopt new-type circuit; this high-performance electronic ballast has High Power Factor, low crest ratio, low harmonic content; adopt own two patented technology electronics preheating starters and abnormity protection circuit to constitute high-performance electronic ballast; the circuit elements device is few, to the advantage of fluorescent tube switch life raising more than seven times.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the circuit diagram of the utility model high-performance electronic ballast.
Among Fig. 1: a high-performance electronic ballast of forming by semiconductor device, it is characterized in that: import an end by alternating current 220V and connect resistance (R0), resistance (R0) other end connects electric capacity (C0) upper end and inductance (L1) winding head end, inductance (L1) winding tail end connects electric bridge (D1) ac input end, inductance (L1) second winding one end connects electric capacity (C0), inductance (L1) the second winding other end connects the other end of the ac input end of electric bridge (D1), the anode of the dc output end of electric bridge (D1) connects electric capacity (C1), electric capacity (C9), diode (D12) anode, the other end that diode (D12) negative terminal connects electric capacity (C9) is the A end, the positive supply of power supply sub-ballast, electric bridge (D1) direct current output negative terminal connects electric capacity (C2), electric capacity (C10), diode (D13) negative terminal, the anode that electric capacity (C10) other end connects diode (D13) is the B end, power supply sub-ballast negative supply, the other end of electric capacity (C1) and electric capacity (C2) link together and are fluorescent tube cathode return circuit in the C end power supply sub-ballast.
