4 ·使用A C電源功率因數高，其輸入電壓可工作予A C 電源整個周期，因此無需調整電源功率因數P F C。 5 ·工作電源可使用DC12V以上，及AC110/2 2 0 V，因此在U P S不斷電系統應用上，不需再經 過轉換單元而可直接使用。 6 ·因工作電壓額定不受輸入電壓影響，在市電使用上， 不再受限於市電不穩定的影響，即使市電降低依然可 穩定工作。 7 ·其相關可應用之產品廣泛，係包含有：電源供應器、 安定器、變頻器、換流器、變壓器等需要電力轉換的 1281308 產品，可令產品不再有A C/D C之分，達到只要有 電便可使用之功效。 即，可給予不同的輸入電壓，其工作電壓依然維持額 定的交換式電源供應器，其設計多樣化易於大量生產，而 工作電壓可依功率晶體耐壓而定，因此，無須依輸入電壓 決定功率晶體耐壓，如此可降低功率晶體使用成本，再者 : ，透過變壓器初級線圈對諧振電容充/放電，使得諧振電 ; 容兩端電壓與輸入電源做相對應的變動，進而不影響工作 ® 電壓，因此，無論輸入電壓是穩態或非穩態，其工作電壓 都能夠維持穩定，亦因工作電壓額定，所以各線圈的脈波 寬幅變動降低，使得在電路應用上無論是R C C振鈴抗流 圈變換器.FLYBACK返馳式.FORWARD前向變換器或PWM 定頻電路均可減小積體降低成本。 本發明顯係利用自然法則之技術思想之高度發明，亦 有實質功效增進與產業上的高度利用性，完全合於發明專 利之法定要件，爰依法提出發明專利申請。 【圖式簡單說明】 ； 第一圖，係爲習用返驰式拓撲基本電路圖。 : 第二圖，係爲習用順向式拓撲基本電路圖。 第三圖，係爲習用推挽式拓撲基本電路圖。 第四圖，係爲習用電容器輸入返馳式拓撲基本電路圖。 第五圖，係爲本發明之電容耦合返驰式諧振吸收電路圖。 第六圖，係爲本發明之變壓器耦合返驰式諧振吸收電路圖 1281308 路圖 【主要元件符號說明】 •···整流元件 11 ’功率因數調整級 • · · ·變壓器 2 1 •第二次級線圈 21 •··諧振電路 22 • ••開關元件 23 •譜振回授電路 24 作電壓穩定電路 25 第七圖，係爲本發明之變壓⑽合^切振吸收電路圖 =圖’係爲本發明之電容變壓_合推故式魏吸收電 1 2 · 2 1 · 2 12 2 2 · 2 3 · 2 4 · 2 5 · 工 • · · · ·電容 # · · · ·功率級 •••初級線圈 •第三次級線圈 •••諧振電容 • ••開關元件 儲能/除能電感 • ••穩壓電容4 • The A C power supply has a high power factor and its input voltage can be applied to the A C power supply for the entire period, so there is no need to adjust the power factor P F C. 5 · The working power supply can use DC12V or above and AC110/2 2 0 V. Therefore, in the U P S uninterruptible power system application, it can be directly used without going through the conversion unit. 6 · Because the working voltage rating is not affected by the input voltage, in the use of commercial power, it is no longer limited by the instability of the mains, and even if the mains is reduced, it can still work stably. 7 · Its wide range of applicable products include: power supply, ballast, inverter, inverter, transformer and other 1281308 products that require power conversion, which can make the product no longer have AC/DC points. As long as there is electricity, you can use it. That is, different input voltages can be given, and the operating voltage is still maintained at the rated switching power supply. The design is diversified and easy to mass-produce, and the operating voltage can be determined according to the power crystal withstand voltage. Therefore, it is not necessary to determine the power according to the input voltage. The crystal withstand voltage can reduce the power crystal use cost. In addition, the resonant capacitor is charged/discharged through the primary coil of the transformer to make the resonant power; the voltage across the capacitor changes correspondingly to the input power supply, and thus does not affect the working voltage. Therefore, regardless of whether the input voltage is steady or non-steady, its operating voltage can be maintained stable, and the operating voltage is rated, so the pulse width variation of each coil is reduced, making RCC ringing anti-flow in circuit applications.
