In addition, the switching power supply used by computers not only uses a large number of parts, but also has a large volume, and the efficiency is only up to 85%. It is often caused by the high temperature of the working environment in the computer hard body. Applying it to a lamp, it is foreseeable that the user has to pay considerable maintenance costs.

Here, the LED lamp set of the current learner is a switching power supply device for a general computer, and the design principle is a constant voltage constant current device. However, because LED bulbs are characterized by changes in physical properties as they accumulate over time. For example, the operating current will gradually increase with the increase of the number of hours of use.

Then, please refer to the review board as shown in the second figure. The creation is based on the power factor requirement of the lamp stabilizer above 30W, and the power factor correction circuit 4 (PFC) is designed in the system. The wafer 6 (STL6561) used in the correction circuit 4 (PFC) has the following features: 1. Undervoltage lockout function with hysteresis. Second, low starting current (typical: 50uA; guaranteed below 90uA), thus reducing power loss. 3. The internal reference voltage has an error rate of less than 1% at 25 °C. 4. In addition to the Disable function, the system can be turned off when needed to reduce losses. Five, two levels of overvoltage protection. Sixth, with internal start and zero current detection. Seven, with a multiplier, for a wide range of input voltage, there is a better THD value. 8. At the current detection input, there is an internal RC filter. < Nine, high-capacity totem-level output, can directly drive the gold-oxygen half-field effect transistor (ship SFE: T). The creation of the wafer 6 (ST L6561) used by the power factor correction circuit 4 (PFC) has a so-called transient mode technique design to obtain the voltage required for the LED lamps to be connected in series. Current control is used to achieve the purpose of making the input current Sin waveform and achieving the same phase of current and voltage. First, when the AC main power supply is passed through the bridge rectifier circuit 3KU4KB80R), it is sent to the boost converter (refer to the first figure), and the boost converter using the switching technology can convert the input voltage to our demand. Output voltage value. When the error amplifier compares the sampled voltage outputted by the boost converter with the internal reference voltage and produces a signal proportional to the difference between the two; if the bandwidth of the error amplifier is sufficiently small (less than 2〇nz), the error signal It can be regarded as a constant flow value in half a week. The error signal will be sent to the multiplier and multiplied by the rectified input sampling voltage. The product result is a rectified waveform with peak value and main voltage peak value and error. The amount of signal is related; 'The output of the multiplier is sent to the 'terminal' of the current, the reference signal of the Siri waveform of the PWM, when the voltage of the 1C current detection (CS) pin64 of the chip 6 (ST L6561) is the inductor current and When the voltage of the resistor is equal to the current comparator and the voltage at the terminal is equal, the conduction action of the gold oxide half field effect transistor 81 (m〇sfet) Q1 is cut off; if it is inferred, the current of the inductor 321 (L1) current will be It is the rectified Sin waveform. It is possible to prove that the system has a fixed on-time during each half-cycle operation. From the MOS half-field effect. M341806 Γ : • ...... • Crystal 81 (MOSFET) Q1 cutoff To inductance When the current of 321 (L1) is zero, the inductor discharges the load; it can operate. When the current of the inductor 321 (L1) is zero, there is no energy storage on the inductor 321 (L1) and the drain pole 33 (D1) is in the floating state. At this time, the total capacitance of the inductor 321 (L1) and the drain 33 (D1) resonate, and the voltage of the drain 33 (D1) quickly falls below the instantaneous line voltage, and the signal triggers the gold-oxygen half-field power again. The transistor 81 (MOSFET) Q1 turns on and another conversion cycle begins. This small voltage across the gold oxide half field effect transistor 81 (MOSFET) Q1 can reduce the switching loss and the energy stored in the equivalent capacitance of the drain 33 (D1) when turned on (loss on the gold oxide half field effect transistor 81) (MOSFET) Q1 internal) loss. In addition, (see the second figure) the inductance, 321 (L1) current and the result of crossing the gold-oxygen half-effect transistor 81 (MOSFET) Q1 in the time interval, can be proved by the geometric relationship, from the main The average input current drawn by the line is exactly half of the peak current waveform of the inductor. System operation is close to continuous and not • Lai Lun boundary mode. Referring to the third and remaining diagrams, the output voltage of the bridge rectifier circuit 31 (U4KB80R) is divided by the resistor 92 (R7, R8) and can be applied to the first pin pin 61 of the chip 6 (ST L6561). A feedback voltage proportional to the output voltage is obtained. This voltage is compared with the reference potential of 2·5V inside the 1C, and then passed through the first pin pin61 of the chip 6 (ST L6561) and the second pin of the chip 6 (ST L6561). The compensation network output at both ends of pin Pin62 is used as one of the internal multiplier inputs; at the same time, the 60Hz power supply voltage is divided by resistor 92 (R9, R10), and is obtained on the third pin ρίη63 of the chip 6 (ST L6561). A sinusoidal voltage Vs(1) is also another input source of the multiplier. After the two voltages are multiplied by the multiplier, a sine wave reference voltage Vr(1) is obtained, and the sine wave reference voltage Vr(1) is used as a power switch. The basis for the timing. When the seventh pin pin67 gate drive signal of the chip 6 (STL6561) causes the metal oxide half field effect transistor 81 (M0SFET) to turn on. Q1 is turned on, the current of the inductor 321 (L1) rises according to the di/dt slope, and flows through the sense resistor. 92 (R6), taking the voltage across the resistor 92 (R6) % via the chip 6 (ST L6561) 1C current detection (CS) ρίη64 compared with the reference voltage VrW, when VAVrw, wafer 6 (ST L6561) The seventh pin Pin67 drives the metal oxide half field effect transistor 81 (MOSFET) Q1 to turn off. The purpose of the other set of auxiliary coils is to provide the control of the switch conduction in addition to the stable power supply of the chip 6 (STL6561). When the gold oxide half field effect transistor 81 (MOSFET) Q1 is turned off, the polarity of the main coil is reversed, and the auxiliary coil is At time, it becomes a positive potential, and the reference potential of the eighth pin pin68 (Vcc) power supply of the wafer 6 (ST L6561) and the fifth pin pin 65 of the wafer 6 (ST L6561) is supplied. When the energy of the main coil is released, the potential of the auxiliary coil also drops, so the reference potential of the fifth pin pin65 of the wafer 6 (stl6561) decreases, due to the inside of the fifth pin Ρίη65 of the wafer 6 (ST L6561). The circuit is triggered by a negative edge. When it drops below 1.8V, it triggers the internal and makes the gold oxide half field effect crystal•M341806,” Α body 81 (MOSFET) Ql is turned on, so the average current waveform obtained by active PFC can be seen. As a complete sine wave, and its phase is in phase with the AC power supply, the PF value obtained by active power factor correction can be up to 0.98.
