INSTRUCTION DESCRIPTION (1) 1 TECHNICAL FIELD OF THE INVENTION The present invention relates to a regenerative energy DC power supply system, and more particularly to a regenerative energy DC power supply system having a power balance and a mains parallel function. [Prior Art] Since renewable energy generation is susceptible to weather, time and location, resulting in unstable power generation, if solar energy, wind power and other renewable energy can be operated in parallel and simultaneously integrated into the mains, it will not only improve the reliability of power supply. It can also suppress the peak load of the Taipower generator set. _ Traditionally, the block diagram of the renewable energy mains parallel system is shown in the first figure. A renewable energy supply system 10 provides renewable energy and stores the battery pack 14 via the charge/discharger 12. Battery pack 1 The energy of 4 is fed to the DC side of the DC/AC converter 18 by the charge/discharger 12 and the DC/DC booster 16, and the DC power is converted by the DC/AC converter 18. AC power is supplied to the load 20. When the energy is insufficient, the power required by the load 20 is provided by the mains 2 2, but the system requires a multi-stage converter and an energy storage battery pack, so the price is high and the efficiency is low. In response to the above-mentioned shortcomings, 遂 developed a regenerative g source mains parallel architecture as shown in the second figure. This architecture does not require a battery pack and a charge/discharge device for energy storage. In this architecture, when the regenerative energy is supplied to the load 2 After 4, the remaining power can be fed into the mains 2 2, but a DC/DC booster 26 is still required. As shown in the third figure, the regenerative energy mains parallel architecture adopts a single-stage design. Although the system efficiency is high, there is still a DC power supply that cannot provide a stable potential, a single potential on the DC side, and low power supply reliability. , the function of the converter
1276298 五、發明說明（2) 率開關元件電流應力大等缺點。 此外，就再生能源與市電併聯供電系統的拓撲結構而 言，如第四（a)圖與第四（b)圖所示，可分為串聯型與並聯 型供電。如第四（a)圖所示，串聯型架構雖然較為簡單， 但其缺點為若其中有一組電源飄動過大或者失效時，則其 它組電源將無法提供補償電壓，使得負载2 8電壓不足，無 法滿足負載28的需求；而並聯型架構，如第四（b)圖所 示，雖然不會因為其中一組電源飄動過大或失效而影響到 電源輸出級3 0的動作，但在傳統技術上並聯型架構係採用 器來傳送能量，且利用分時控制的方式操控各電源輸 入級3 2、3 4的功率開關，將使得各電源輸入級3 2、3 4所具 有的工作時間因輸入級的增多而其時間相對更少，致使輸 出受到限制。因此，多電壓源輸入之供電系統架構，仍有 待改善。故針對上述所述之缺失，中華民國專利公開號 2 0 0 4 1 7 1 0 7提出如第五圖所示的架構，為一般具備雙、單 向之再生能源與市電併聯系統，雖然此系統具有雙向控 制，但實現時卻需要許多功率開關元件，而且無法達成主 動電力濾波、改善功因與雙直流電位供電等功能。 _ 有鑑於此，本發明係針對上述之問題，提出一種具市 ^併聯功能之再生能源直流供電系統。 【發明内容】 本發明之主要目的，係在提供一種具市電併聯功能之 再生能源直流供電系統，其可將剩餘的電力饋入市電端， ά有效地提高再生能源發電設備的利用率，而於再生能源1276298 V. Description of the invention (2) Shortcomings such as high current stress of the switching element. In addition, as for the topology of the regenerative energy and the commercial parallel power supply system, as shown in the fourth (a) and fourth (b) diagrams, it can be divided into series and parallel type power supply. As shown in the fourth (a) diagram, the series architecture is simple, but the disadvantage is that if one of the power supplies is too large or fails, the other groups of power supplies will not be able to provide the compensation voltage, so that the load 28 is insufficient. Satisfying the demand of the load 28; and the parallel architecture, as shown in the fourth (b) diagram, does not affect the action of the power output stage 30 because one of the power supplies is too large or fails, but is connected in parallel in the conventional technology. The architecture adopts a device to transmit energy, and the power switch of each power input stage 3 2, 3 4 is controlled by means of time-sharing control, so that the working time of each power input stage 3 2, 3 4 is due to the input stage Increased and relatively less time, resulting in limited output. Therefore, the power supply system architecture of multi-voltage source input still needs to be improved. Therefore, in view of the above-mentioned shortcomings, the Republic of China Patent Publication No. 2 0 0 4 1 7 1 0 7 proposes an architecture as shown in the fifth figure, which is generally a dual, one-way renewable energy and commercial parallel system, although this system It has two-way control, but it requires a lot of power switching components, and it can't achieve active power filtering, improved power factor and dual DC potential power supply. In view of the above, the present invention is directed to the above-mentioned problem, and proposes a regenerative energy DC power supply system having a parallel function. SUMMARY OF THE INVENTION The main object of the present invention is to provide a regenerative power DC power supply system with a commercial power parallel function, which can feed the remaining power into the commercial power terminal and effectively improve the utilization rate of the renewable energy power generation equipment. renewable energy

Description of the invention (5) When the load of the two live wires is different, the voltage will be unbalanced. In order to avoid such power instability, the present invention utilizes a connection to the load. The power balancer 44 of 42 stabilizes the voltage of the two live lines to the ground line so that when the load of the two live lines is different, the ground potential of the ground potential can be broken, and the balance of the power balance is ί. As shown in the sixth figure, the electric scale 44 of the present invention is * two capacitors 44 串联 in series, "2 parallel two H-opening elements 444 in series, "6, for example, a diode, and an inductor is connected in the middle. And, it has the advantage of simple structure; when the load of the two live wires is different, please refer to the sixth figure and the seventh figure at the same time, the balance balancer ^ is correctly controlled by two power switching elements 444, The switching of 446 causes the electric valleys 4 4 0 and 4 4 2 to be respectively charged or discharged, and the voltages of the two live lines to the ground line are balanced, thereby stabilizing the power supplied to the load 42. - As shown in the sixth figure, the active de-coupling control circuit 46 of the present invention is connected to an electrolytic capacitor 462 by a Schottky Diode 460, except that the architecture is simple and does not require any active switching.
