Case No. 922010M V. Creation instructions (1) [New creation area] This creation mainly relates to a low-harmonic electronic ballast driving circuit, which refers to a driving circuit that changes the switching type of the driving circuit to gain low-harmonics .

The conventional circuit of general gas (the function of magnetoelectromotive force generated by the process of absorbing purple emitted by electricity release is to be accessed is traditionally gradually achieved enough to realize that the device has two bridges to each other) and the moving circuit is replaced by AC technology]: fluorescent lamps are mainly After the external light is added to the UV light, the field will follow.) From the stabilizer, the electronic stabilizer of the stabilizer is still better. The half of the general rectification compensation type requires two power sources. The energy flow in the lamp sector is driven by the body-driven tube system. After the mercury atoms of the lamp tube excite the argon gas (also including the gas neon or nitrogen krypton) at high pressure, it will frequently collide with the gas atoms. Visible light is then released again by various fluorescent substances on the inner surface of the tube. Because the fluorescent lamp is discharged by gas and the current flows from the coil during this process, the surrounding changes will cause the magnetic flux in the coil to change (while the fluorescent lamp should not be directly connected to the AC power source, it usually changes by% 疋 current. In addition, the ballast generates high voltage for daylight to reach the start of the fluorescent lamp. F The weight and volume are too large, the noise is high, and it is easy to leak electricity. The industrial equipment has replaced it with a lighter weight and a smaller volume and power.

One part of the basic structure of the electronic ballast is composed of a bridge rectifier, a road and a wave capacitor, and the other part is a piezoelectric crystal (M0SFET, metal-oxygen half-field effect transistor DC / AC converter, which constitutes a driver). Circuit, with 1 piezoelectric crystal switched at different time points, DC can be changed

Correcting Γ (THD) will destroy the carrier control information in the power line = generating dangerous high current, so the industry has adopted this standard and adopted multiple control methods. If you apply for the patent application No. 7 or 8 (granted patent): & Use the drive circuit with two complementary thunder and / / output terminals to avoid the formation of a round of positive and negative power to reduce the transistor loss m, the same = pass The instantaneous current pulse, the load of the capacitor is made up of the diode and the effect of losing straightness. The “circuit” industry has achieved high power and low harmonic gate driving of-^^^ npn / p'npf. However, in the case of Pi Kai: Although V is suitable for power transistors, and NPN / PNP (Bidirectional Diode) product, and the power consumed by the gate is proportional to environmental factors, such as tide, county, etc. Baojue ^ In addition to the on-site work, the instability of the evil affects the stability of the waveform: the first-grade erosion, and even the power supply with bidirectional diodes will increase due to the ancient finger consumption. It is miniaturized with the same frequency, but this is high, and the reliability of the lead is reduced. Increased polar body loss will cause temperature rise. New content]: In view of low harmonic distortion, and its effect and voltage stability for the electron # a ^ Gu Faxian, the first polar body element is depleted, so I think there should be a kind of I = = i = Stability and safety of electricity use. This innovation reduces the lamp's filament electricity, ☆ 3 circuits' to solve the problem of stable voltage and voltage stability.

Because of the resistance (V = IR) ', only the transistor needs to be compared, and the driving with a lower voltage is more stable. Method]: Create a driving circuit with a resistance switch R3 to provide a micro switch to start the inductor. Use circuitization to avoid the use of NPN / pNp (dual body), which is susceptible to the area of the waveform, which is proportional to the power consumed by the gate. 2 On-site Outside work, the influence of harsh environmental factors, such as humidity and corrosion, reduces the stability of the waveform generated by the instability of the power supply.
