Description of the invention: [Technical field to which the invention belongs] - Viewing the power to retreat from the enchantment, especially as the power factor correction unit wipes the capacitance decay. [Previous technology] of the current electric power supply device Nowadays, the power supply device has been widely applied to various kinds of lightning. The output power is also rising continuously, in order to further improve the power efficiency of the power supply. The factor mainly includes the input power, and the (four) object correction private (Ρ_Μ 2 kiss η: _ is PFC) is an important circuit for improving the number of input power power, especially the active power correction single 7C will increase the reading scale. To the jumping club, and the power supply including the power, the school power source obtains - input power, the input power passes; after the flow = the power factor correction unit modulates the phase of the input power 're-power- The conversion single pain becomes an output voltage, wherein the power conversion unit can be a converter ConverteO or a switching type conversion circuit, and the side correction unit and the electric conversion unit are respectively operated according to the control unit. The typical power factor correction unit includes a switching component, an inductor component, an inductor component, and the control unit, wherein the control unit obtains a feedback signal from the back end of the power factor correction unit to generate a period control. Touching the component, riding the inductive component without a capacitive component to modulate the phase of the input power. The principle of the power factor correction unit is well known to those skilled in the art field, and therefore will not be described again; The power factor correction unit also has its service life. Most of the faults of the power factor correction unit are due to the fact that the capacitor element will decay rapidly after the power fluctuation of the input power for a long time, and in order to absorb the power fluctuation, it must be selected. The electrolytic capacitor component with large capacitance value and high withstand voltage cannot be reduced in cost. Please refer to Figure 1 and Figure 2, where Vg represents the electric power M of the input power, and % represents the voltage of the capacitive component of the power correction unit. And v〇 is the output voltage of the back-end power conversion unit, wherein the product of the voltage Vg of the input power and the current iin of the input power is the transient input power Pin of the input power (as shown in FIG. 2), and the fluctuation of the power The larger the energy, the greater the energy required to be absorbed and released by the capacitive element, causing a rapid decay of the capacitive element; the reference circle i and Fig. 2 5 201006106 "two", with great fluctuations The output of the power factor correction circuit is the voltage of the price '. The power fluctuation of the visible input power is almost the same as the capacitor element, L and ", although it can provide a high power factor', but the capacitive component is subjected to a large冲=城与她, the above-mentioned conventional work factor correction unit is wasteful due to the decay of the capacitor due to the decay of the capacitor. For example, when the light-receiving diode is used, the above-mentioned conventional power factor correction unit is used. The lifetime of the polar body itself to 2, 1], but due to the attenuation of the capacitive element, the work cannot be operated due to the correction of the shot (the average life of the electrolytic capacitor element), and this is the power factor correction single (four) circuit board. And the light-emitting diodes soldered to them must be

The lifetime of the correction unit is limited by the life of the capacitor. Therefore, the purpose of this = is to provide a control strategy to improve the lack of knowledge and extend the service life of the capacitor and the power factor correction unit. . Invented as a power supply for improving capacitance degradation, the power supply has a work = correction unit and a power transfer element, and the dance is that the side correction unit has - - energy storage, the power conversion shirt has - Switching the modulation circuit, the fluctuation amplitude Ε of the input power is divided into a first-amplitude energy Ει and a second amplitude energy Ε2, and the first-near element absorbs the first-difficult energy & The 〇 input power still has a fluctuation of the first amplitude energy & and the switching modulating loop will have the second amplitude energy E2 modulated to DC power to form an output power of _; The handle (four) surface is not the same as the electric power, but has the voltage of the sister wave, such as the ❹卩 赖 度 , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , , In comparison, since the capacitance reading capacity of the correction circuit t is large, the output of the conventional power correction unit is almost Hengqian County, and the __ small-capacity capacitive element is the first-amplitude energy E in the input power. l, so that the output of the power factor correction unit is no longer the traditional power factor correction 6 201006106 single το output '1ι_定杂' but a large ripple power, so you can greatly reduce the storage capacitor capacity The value reaches the effect of extending the work of the positive _ positive unit.
