have fluorescent lamp ballast integrated circuit of power ...

The fluorescent lamp ballast was designed and all electronic lighting systems were modified.Compared with the equipment five years ago, the increasingly mature electronic ballast technology can provide better features at lower system costs.The most representative of the IR2166 and IR2167 control integrated circuits is the new generation of electronic ballast control integrated circuits.
• There is no audible noise • Easy increase in power factor correction • The flashing consideration of the light is very important, because the magnetic ballast flashes when 60 hz is working.Compared to this, the electronic ballast converts the high frequency to the intersection of 60 hz and power, so it flashes and reduces the light to an experienced capability.In addition, there is one less high-frequency heat and the efficiency is higher.
Due to the operation of use, the magnetic ballast will produce audible noise in the core EMC element of 60Hz, it will not emit audible exchange hum to design excellent high levelElectronic ballast of frequency.Power factor correction (PFC) can easily be added to all types of electronic ballasts, but it is very difficult for magnetic ballasts.The power factor correction circuit can correct the AC, change the input voltage and current flow to a sine wave, and increase the harmonic content.
In addition, by receiving a high power factor, the efficiency is also improved and the cost is reduced.The harmonic objective of the ballast is to maintain the international standard IEC 61000-3-Class 2 C is less than the harmonic current limited by the lighting system.The power factor correction is also related to the total harmonic distortion (THD, that is, the power harmonic generated by the ballast.
Any harmonics generated by the ballast will also have adverse effects on other electronic systems connected to the same power supply.Power factor means that the input power is pure wave and there is no harmonic distortion (THD is 1.0 = 0%), so it is better to have high power factor (PF) and Low THD.
After determining the adoption of all electronic schemes, the designer needs to consider multiple electronic schemes used in the lighting system and control the properties of the IC.These features affect the entire system cost of an electronic ballast.The biggest cost factor may be the number of components used, which affects the preservation of hardware, the overall arrangement of components and the whole project.
The main question is: can an IC provide a complete ballast to control?An integrated circuit reduces hardware costs and simplifies the ballast to the interface of the lamp.Is IC suitable for wide light type and sizerange?Storing a piece of IC suitable for all system configurations can reduce hardware inventory.Can the control IC be programmed to set up system functions according to application requirements?This can make the system design more flexible.
Is the IC built in?Power factor correction (PFC )?The built-In the power factor correction circuit, the number of entire components can be reduced.Is there a display board?It can simplify the design of the lighting system.Is there a computer-aided design software for the demo board?It can help designers reduce the time it takes to market their products.
IR2166 and IR2167 give the answers to the above questions are \\\".The old generation electronic ballast control device adopts the September control IC, gate drive IC and pfc ic, and the IR2166 and IR2167 adopt the single chip microcomputer scheme, which reduces the system cost.In addition to reducing the number of components, these integrated circuits simplify installation, improve reliability and save design time.
In addition, they have reduced the time for new fluorescent lighting systems and put them on the market.The IR2166 device has a state machine for controlling the order of work of the ballast, including under-voltage locking, preheating, triggering, operation, and failure modes.The chip integrates programmable preheating time and frequency to heat the wire to a suitable transmission temperature.
This property can extend the life of the light.Span 30 times Daming while reducing the required trigger voltage.The features of programming dead time, preheating, and operating frequency make the IR2166 adapt to many different types of lights by modifying the component brieflying.
In addition, the general 90 v can be designed as a simplified circuit for 260 v ac inputs in the global market, reducing the need for special planning for different regions.The fluorescent lamp ballast was designed and all electronic lighting systems were modified.Compared with the equipment five years ago, the increasingly mature electronic ballast technology can provide better features at lower system costs.
The most representative of the IR2166 and IR2167 control integrated circuits is the new generation of electronic ballast control integrated circuits.In order to understand the related properties of these two integrated circuits, we first see that they can compensate for the characteristic advantages of the weak points of the magnetic ballast, including: • There is no audible noise • Easy increase in power factor correction • The flashing consideration of the light is very important, because the magnetic ballast flashes when 60 hz is working.Compared to this, the electronic ballast converts the high frequency to the intersection of 60 hz and power, so it flashes and reduces the light to an experienced capability.
