Transformer


There is no overlap bias settings. In addition, the secondary residual circle (4.5) conductive interconnect, where the total resistance of up to 20. The transformer according to the invention particularly suitable as a high-voltage ignition with a small discharge lamp ignition transformer, for example halogen such as mercury-free - a high-pressure metal vapor discharge lamp. Bulletin No. C544493Y Name Abstract A halogen halogen electronic transformer electronic transformer, including the interference by one connected to the circuit, the rectifier circuit, delay circuit, switching amplifier, pulse width modulation control circuit to limit self-oscillation circuit and output circuit, including: delay circuit consists of diode D7, resistors R2, R3, capacitor C4, and thermal protection consisting of resistor Rt; switch by the transistor amplifier circuit,,-n, T2, resistors R4, R5, R6, R7, R8, L6, 135 two-way control, diode D6, 138,139,1) 10, Dll, capacitors a, C8, C13, SCR,,-r3 formed; limited self-oscillating circuit consists of two parallel reverse Diodes D12, D13 formed. The utility model is not only instantaneous short-circuit protection in power is very reliable, and long lines in the short-circuit state will be in a state of absolute reliability, short time no matter how long the line will not burn. Also added to start the moment the voltage on the lamp load is only about lV, making lamp life. Publication Number CN1416212A name low-frequency electronic power transformer Abstract A low-frequency electronic power transformers, including lightning and electromagnetic compatibility components, rectifier and inverter; its characteristics are: low-frequency inverter as described in the inverter, the frequency inverter consists of two switch as the core switch circuit, a voltage divider consisting of the capacitor circuit, connected to switch control terminal of the delay start circuit,franklin marshall femme, driver transformer, inverter transformer and the protection module; inverter transformer T221 primary coil and drive coil input transformer 13 connected in series L3C two switch output circuit, T3, two output coils L3A, L3B, respectively connected to two switch input circuit. T2 secondary output AC rectangular wave voltage. The operating frequency is 200 ~ 750oHz, light weight, high reliability, high efficiency, high power factor, long life, electromagnetic compatibility, AC output distance, low cost and small size, and many other features to address the electronic transformer heating problem, the requirements of the components also declined significantly, widely used in electronic products, lighting and other products. Bulletin No. CN2583928Y names from the summary recovery of electronic ballast with electronic ballast from the recovery, which involves an electronic ballast, specifically a high-intensity gas discharge lamp electric converter sheet. Ballast protection circuit by the protection signal detection circuit, signal circuit protection, protection signal detection circuit of the induced current signal CL1 current sensor input termination at one end, the protection signal detection circuit of the two signals input termination voltage discharge lamp Ll of the two power supply terminal, protection signal detection circuit detects the signal output terminal protection signal circuit signal input side, to protect signal circuit of the signal output terminal high voltage start-end and high-frequency inverter control circuit controls end; the utility model with self-recovery, failed to start for the lights, heat lamps, lamp open circuit, short circuit and other light non-normal state, can automatically protect; this to the actual use and maintenance is a big . Publication Number CN1457222A name electronic ballast flicker free summary of the present invention relates to a non-stroboscopic light-emitting devices and electronic ballasts is to eliminate high-frequency electromagnetic pollution and design. No flash electronic ballast, including the exchange of rectifier circuits, DC-AC inverter and the starter light circuit,ralph lauren pas cher, the DC-AC inverter in the above light emitting device and the connection between the rectifier circuit. Also containing the non-strobe light-emitting device of electronic ballast. The invention has the advantage of using direct current to the load light, so there is no high-frequency pollution, and safety to eliminate flicker. Can protect the eyes, and environmental pollution, the role was a stroke two. Bulletin No. a,abercrombie paris, i2539379Y. Name resonant switching electronic ballast Summary The present invention of a useful electronic fluorescent ballast circuit, the half-bridge circuit, starting circuit, ballast inductors, control and drive circuit. FET M1, M2 and capacitor C1, (: 2 to form a half-bridge circuit, lamp load connected through a ballast inductor U to point A, the other end connected to the tube at point B,, RT1, Ln form lamp start circuit control and two phase output drive circuit 180 ', the frequency f is constant throughout the voltage signals, drive
