交流電源0，和在商用交流電源0經由濾_電路1連接之 做爲整流電路的二極體橋路2，和連接在二極體橋路2的 輸出端子之平滑電容器3，和具有1次及2次繞組4 a ， 4 b的變壓器4，和連接在平滑電容器3之兩端的變壓器 4之1次繞組4 a與做爲開關元件的MOS — F ET5之 串聯電路。圖2 2的直流轉換裝置之動作係如下。從商用 -ν’.- . 交流電源ί)的交流輸入將經由濾f電路1根據二極體橋路

商用交流電源0，濾波器電路1，二極體橋路2及平滑電 容器3形成的轉換器输入部係成爲所謂電容器輸入型，所 以如圖2 3 (B)所示地交流输入電流IIN只在圖2 3 ( A )所示的交流输入電壓VIN之最大值附近才有，而將成 爲脈波狀的交流输入電流波形。因此，具有交流输入之功 率因素會低至0.5〜0.6程度的缺點。要改善交流输 入之功率因素時，例如在整流電路插入電感充份大的抗流 線圈即可，但是具有抗流線圈大形且重量會變大之缺點。 同時，雖然最近也有設置功率因素改善用的前置轉換器， 電子性地改善功率因素之活性轉換方式的提案，但是該方 式係零件數也多，具有大型化，髙價格化，互相干擾等之 缺點。 因此’本發明之目的，係在提供能以簡單的電路構成 經濟部中央揉準局員工消费合作社印製 (請先聞讀背面之注意事項再填寫本頁) 改善交流输入之功率因素同時小型而輕量的直流轉換裝置 〇

因爲抗流線圈係以比交流電源之頻率極高的開關元件之開 關頻率使用，所以電感小者也可以。因此，能夠使用小型 且輕量的抗流線圈。所以能夠設法使直流轉換裝置小型化 及輕量化。 〔實施例〕 以下，根據圖1及圖2說明本發明的直流轉換裝置之 一實施例。但是，在此等圖面中和圖2 2及圖2 3所示者 實質上相同的部份將附以相同記號而省略其說明。 本實施例的直流轉換裝置，係如圖1所示，在圖2 2

0的第2繞組1 Ob及二極體1 1施加在平滑 電容器3，而將平滑電容器3充電。在MOS — FET5 的閘端子供給控制信號使MOS — FET5 ON - 0 F F動作時，平滑電容器3兩端的電壓會斷續地施加在 抗流線圈1 0之第1繞組1 0 a及變壓器4的1次繞組 4a ，當MOS — FET從ON狀態成爲OFF狀態時， 將在2次繞組4 b誘起電壓。變壓器4的2次繞組4 b之 誘起電壓，將由整流二極體6及輸出電容器7而成的整流 平滑電路整流平滑，而在輸出端子8，9間將發生直流輸 出。與此同時，在抗流線圈1 0的第1繞組1 0 a將斷續 地通電而在第2繞組1 0 b會誘起交流電壓》在抗流線圈 1 0的第2繞組1 0 b誘起之電壓，將根據二極體1 1整 流而施加在平滑電容器3，把平滑電容器3充電。因此， 此時施加在平滑電容器3的電壓，將成爲二極體橋路2之 全波整流输出電壓重叠在抗流線圈1 0的第2繞組1 0 b 誘起的電壓者。此時，因M0S — FET5之控制信號 的頻率係比商用交流電源0之商用頻率（5 0〜 60Hz)高出很多（10k〜200kHz)，故在抗 流線圈1 0的第2繞組1 0 b誘起之電壓，將成爲比從平 滑電容器3的兩端之電壓減去二極體橋路2的全波整流輸 出電壓之電壓大。因此，在二極體橋路2的全波整流輸出

[Conventional Techniques] DC converters that convert AC power supplied from commercial AC power sources, etc., into DC power have been widely used in the field of electronic equipment and motors in the past.

The operation of the DC converter in Figure 22 is as follows. The AC input from the commercial -ν ’.-. AC power supply) will be full-wave rectified according to the diode bridge 2 via the filter circuit 1. The full-wave rectified output from the diode bridge 2 will be smoothed according to the smoothing capacitor 3, and the voltage across the slightly DC smoothing capacitor 3 containing the ripple component will be applied to the primary winding 4a of the transformer 4 and the MOSFET The resulting series circuit.

Becomes the so-called capacitor input type, so the AC input current IIN as shown in Fig. 23 (B) is only around the maximum value of the AC input voltage VIN shown in Fig. 23 (A), and will become pulse-like AC input current waveform. Therefore, it has the disadvantage that the power factor of the AC input will be as low as 0.5 to 0.6. To improve the power factor of the AC input, for example, it is sufficient to insert a choke coil with a large inductance into the rectifier circuit, but it has the disadvantage that the choke coil is large and the weight becomes large. At the same time, although there have recently been proposals for a pre-converter for power factor improvement and an active conversion method for electronically improving the power factor, this method has a large number of parts, and has a large size, high price, and mutual interference.

The voltage induced in the second winding 1 0 b of the choke coil 10 will be rectified by the diode 1 1 and applied to the smooth The capacitor 3 charges the smoothing capacitor 3. Therefore, the voltage applied to the smoothing capacitor 3 at this time will cause the full-wave rectified output voltage of the diode bridge 2 to overlap the second winding 1 0 b of the choke coil 10 to induce At this time, because the frequency of the control signal of M0S-FET5 is much higher than the commercial frequency of commercial AC power supply 0 (50 to 60Hz) (10k to 200kHz), the second The voltage induced by the winding 1 0 b will be greater than the voltage of the full-wave rectified output voltage of the diode bridge 2 minus the voltage across the smoothing capacitor 3. Therefore, the full-wave at the diode bridge 2 If the rectified output voltage is lower than the voltage across the smoothing capacitor 3, the Chinese national standard (CNS) will also be applied to the smoothing capacitor 3 according to the voltage induced by the second winding 1 0b of the anti-current coil 10 0.

Description of the invention (21) Sinusoidal resonance voltage occurs at both ends of the first and second MOS-FETs 19 and 20. The current according to the primary winding 4 a of the transformer 4 induces a voltage at the secondary winding 4 b. The induced voltage is rectified and smoothed according to the rectifying and smoothing circuit formed by the rectifying diodes 6 a, 6 b and the output capacitor 7 and output. DC output occurs between terminals 8 and 9. At the same time, the first winding 10a in the choke coil 10 will be energized intermittently, while the second winding 1Ob induces an AC voltage. The AC voltage induced in the second winding 1 Ob of the choke coil 10 is rectified by the diode 11 and applied to the smoothing capacitor 3 to charge the smoothing capacitor 3. Therefore, the voltage applied to the smoothing capacitor 3 at this time will be the voltage induced by the full-wave rectified output voltage of the diode bridge 2 superimposed on the second winding of the choke coil 10. Therefore, the circuit in FIG. 15 can also charge the smoothing capacitor 3 through a wide range of one cycle of the commercial frequency. As shown in FIG. 16 (B), the waveform of the AC input current I will be close to that shown in FIG. 16 (A). The sinusoidal waveform of the AC input voltage VIN shown in the figure can improve the power factor of the AC input like the circuit of FIG. 1. Furthermore, when the first MOS-FET19 is turned on, the surge voltage applied to the diode 11 in the reverse direction will be based on the diode S, so it has the same circuit as the circuit in FIG. 3.
