背景技术Background technique
随着全球科技的不断进步、产业不断升级，电源设备已经成为各种工业设备的心脏，电源系统也发生很大的变化，传统的电源已经不能满足更高的需求。With the continuous advancement of global technology and the continuous upgrading of industries, power supply equipment has become the heart of various industrial equipment. The power supply system has also undergone great changes. Traditional power supplies can no longer meet higher demands.
随着人们对大功率需求的逐渐提升，如何利用电力电子装置实现大功率传输逐渐受到重视。高输出电压等级、高功率密度、高可靠性是现在高压直流电源追求的目标。传统高压直流电源采用的电源方案是输入端接入交流市电，经过升压变压器升压为高压交流电，再整流获得高压输出，这种电源成本较低，技术成熟，但由于采用工频变压器进行隔离升压，使得系统的体积重量难以控制，同时输出电压调节精度也难以控制。As people's demand for high power gradually increases, how to use power electronic devices to achieve high power transmission has gradually attracted attention. High output voltage level, high power density, and high reliability are the goals pursued by high-voltage DC power supplies. The power supply scheme adopted by traditional high-voltage DC power supplies is to connect the input end to AC mains, step up the voltage to high-voltage AC through a step-up transformer, and then rectify to obtain high-voltage output. This power supply has low cost and mature technology, but due to the use of industrial frequency transformers for isolation and step-up, the volume and weight of the system are difficult to control, and the output voltage regulation accuracy is also difficult to control.
随着电力电子器件的发展，高压直流电源经历了从低频到高频、小功率到大功率、低性能到高性能的发展过程。使用开关器件对输入直流进行斩波，使用变压器对高频脉冲升压整流成高压直流，这种电源体积小、效率高。因此开关型高压直流电源逐步取代传统电源应用在各行各业，比如在医疗领域、农业领域、工业领域、军事领域以及科学研究。With the development of power electronic devices, high-voltage DC power supplies have experienced a development process from low frequency to high frequency, low power to high power, and low performance to high performance. Using switching devices to chop the input DC and using transformers to boost and rectify high-frequency pulses into high-voltage DC, this power supply is small in size and high in efficiency. Therefore, switching high-voltage DC power supplies have gradually replaced traditional power supplies in various industries, such as in the medical field, agricultural field, industrial field, military field, and scientific research.

A DC circuit breaker is provided between the output end and the battery. The AC-DC converter is a T-type three-level topology or a two-level topology composed of power-type power electronic switches. The battery is connected to the output end of the converter. When the load size changes, it can be adjusted by the battery. For example, when intermittent loads are added to the system, the intermittent loads can be effectively dealt with by battery discharge, thereby reducing the transformer overload and improving power supply reliability. Directly transmitting all power through power electronic devices has the disadvantages of large device losses and low efficiency. Therefore, in order to further improve the transmission efficiency, some power converters are introduced for power transmission.

下面结合实施例对本发明进行进一步说明：The present invention will be further described below in conjunction with embodiments:
如图1所示，部分功率变换器的结构为两级式DC-DC以级联形式连接在一起，其中前级一般为隔离型DC-DC变换器，后级为电压双象限型DC-DC变换器。总输出电压Vout等于前级输入电压Vin加上变换器输出电压，前级输入电压正极与后级输出电压负极相连，通过后级变换器电压变换，实现升降压功能，同时，可通过调节后级输出电压实现功率分配，大部分功率可直接通过传输线传输，使得部分功率变换器整体效率得到了大幅提升，实现了小功率撬动大功率和高效率的目标。As shown in Figure 1, the structure of some power converters is a two-stage DC-DC connected in cascade form, in which the front stage is generally an isolated DC-DC converter and the rear stage is a voltage dual-quadrant DC-DC converter. The total output voltage V out is equal to the front stage input voltage V in plus the converter output voltage. The positive pole of the front stage input voltage is connected to the negative pole of the rear stage output voltage. The voltage conversion of the rear stage converter realizes the buck-boost function. At the same time, power distribution can be achieved by adjusting the rear stage output voltage. Most of the power can be directly transmitted through the transmission line, which greatly improves the overall efficiency of some power converters and achieves the goal of leveraging high power and high efficiency with small power.
以图2所示拓扑为例，部分功率变换器的结构包括级联形式连接在一起的前后级变换器，前级变换器为两个LLC-DCX变换器以输入串联输出并联的形式组合而成的，可以实现高压大电流的功率输送，其中一个LLC-DCX变换器的具体结构为：Taking the topology shown in FIG2 as an example, the structure of some power converters includes front and rear converters connected in cascade. The front converter is composed of two LLC-DCX converters in the form of input series and output parallel connection, which can realize high-voltage and high-current power transmission. The specific structure of one LLC-DCX converter is as follows:
所述LLC-DCX变换器包括原边开关电路、谐振电路、隔离变压器、副边整流电路和输出滤波电容。谐振电路包括谐振电感Lk、谐振电容C3以及变压器激磁电感Lm。原边开关电路包括四只开关管Q1、Q2、Q3和Q4，开关管Q1和Q3的漏极连接输入正极，开关管Q2和Q4的源极连接输入负极，开关管Q1的源极和开关管Q2的漏极连接，与变压器激磁电感的一端连接，开关管Q3的源极和开关管Q4的漏极连接，与变压器激磁电感的另一端连接。副边整流电路包括四只整流二极管D1、D2、D3和D4，二极管D1、D3的阴极连接输出正级，并连接到后级变换器的一端，二极管D2和D4的阴极连接，并连接到后级变换器的另一端。The LLC-DCX converter includes a primary switch circuit, a resonant circuit, an isolation transformer, a secondary rectifier circuit and an output filter capacitor. The resonant circuit includes a resonant inductor Lk , a resonant capacitor C3 and a transformer excitation inductor Lm . The primary switch circuit includes four switch tubes Q1 , Q2 , Q3 and Q4 , the drains of the switch tubes Q1 and Q3 are connected to the input positive electrode, the sources of the switch tubes Q2 and Q4 are connected to the input negative electrode, the source of the switch tube Q1 is connected to the drain of the switch tube Q2 , and is connected to one end of the transformer excitation inductor, the source of the switch tube Q3 is connected to the drain of the switch tube Q4 , and is connected to the other end of the transformer excitation inductor. The secondary side rectifier circuit includes four rectifier diodes D1 , D2 , D3 and D4 . The cathodes of diodes D1 and D3 are connected to the output positive terminal and connected to one end of the subsequent converter. The cathodes of diodes D2 and D4 are connected and connected to the other end of the subsequent converter.
后级为三相交错并联Buck变换器，可以实现电压双象限调节。The subsequent stage is a three-phase interleaved parallel Buck converter, which can achieve dual-quadrant voltage regulation.
其调压范围由后级三相交错并联Buck变换器确定，当需要进行较大范围电压调节时，可令Buck变换器输出电压绝对值增大，叠加上输入电压后可令输出电压在较宽范围内自由调节。Its voltage regulation range is determined by the three-phase interleaved parallel Buck converter in the subsequent stage. When a wider range of voltage regulation is required, the absolute value of the Buck converter output voltage can be increased. After superimposing the input voltage, the output voltage can be freely adjusted within a wider range.
所述三相交错并联Buck变换器所述三相交错并联Buck变换器为三个并联的Buck电路，其中，三个输出电容合并为一个输出电容，三相Buck输出端的正极作为负载的正极，输出端负极与前级变换器输入端正极相连，负载负极与前级变换器输入端负极相连。The three-phase interleaved parallel Buck converter is three parallel Buck circuits, wherein three output capacitors are combined into one output capacitor, the positive electrode of the three-phase Buck output end serves as the positive electrode of the load, the negative electrode of the output end is connected to the positive electrode of the input end of the previous stage converter, and the negative electrode of the load is connected to the negative electrode of the input end of the previous stage converter.
若要提高变换器整体效率，则可通过降低Buck变换器输出电压来降低变换器输送功率，进而将更大比例的功率直接由传输线从输入送至输出侧，由于变换器输送功率的降低，使得变换器部分损耗得到大幅降低，进而提高了变换器整体效率。If the overall efficiency of the converter is to be improved, the converter transmission power can be reduced by lowering the Buck converter output voltage, thereby directly sending a larger proportion of power from the input to the output side through the transmission line. Due to the reduction in the converter transmission power, the partial loss of the converter is greatly reduced, thereby improving the overall efficiency of the converter.
本发明有助于提高部分功率变换器的效率并提供更宽的输出电压范围，具有较大的工程应用价值和推广前景。The present invention helps to improve the efficiency of some power converters and provide a wider output voltage range, and has great engineering application value and promotion prospects.
