Description

一种共地的高增益Z源升压变换器Common ground high gain Z source boost converter 技术领域Technical field
本发明涉及DC/DC变换器领域，具体涉及一种共地的高增益Z源升压变换器。The present invention relates to the field of DC/DC converters, and in particular to a common ground high gain Z source boost converter.
背景技术Background technique
在可再生能源发电系统中，大多数的可再生能源如太阳能、风能和燃料电池等输出一般都是低等级的直流电压，若要并网的话，需要使用高增益的变换器将低压直流电转换为高压直流电，然后再经过逆变器的作用输出交流电以并网。然而传统的DC/DC升压变换器受到占空比、生热和损耗的限制，无法实现大幅度的升压，如Boost变换器，其电压增益为1/(1-D)，D为占空比，当占空比接近于1时才能获得较高的电压增益，但与此同时会遇到上述的问题；而许多Z源DC/DC变换器，虽利用Z源网络实现了升压，但电压增益仍有提升的空间，如Z源升压变换器的电压增益为(1-D)/(1-2D)，此外还存在不共地、开关管应力较大等问题。In renewable energy generation systems, most renewable energy sources such as solar, wind and fuel cells are generally low-level DC voltages. To be connected to the grid, high-gain converters are required to convert low-voltage DC to High-voltage direct current, and then output AC power through the inverter to connect to the grid. However, the conventional DC/DC boost converter is limited by the duty cycle, heat generation and loss, and cannot achieve a large boost. For example, the Boost converter has a voltage gain of 1/(1-D) and D is occupied. Air ratio, when the duty cycle is close to 1, the higher voltage gain can be obtained, but at the same time, the above problems are encountered; and many Z-source DC/DC converters use the Z-source network to achieve boosting. However, there is still room for improvement in voltage gain. For example, the voltage gain of the Z-source boost converter is (1-D)/(1-2D), and there are also problems such as non-common ground and large switching tube stress.

The first capacitor C 1 and the second capacitor C 2, respectively, to the first inductor L 1 and the second inductor L 2 is charged by the switch S, in addition, the first capacitor C 1 and capacitor C 2 through the second switch simultaneously to the output S Capacitor C out is charged and the load is powered.
(2)在(t1～t2)阶段，变换器在此阶段的模态图如图3b所示，开关管S的驱动信号VGS从高电平变为低电平，开关管S关断，第一二极管D1承受正向电压导通，第二二极管D2承受反向电压截止。直流输入电源Vin和第一电感L1通过第一二极管D1同时给第二电容C2充电，直流输入电源Vin和第二电感L2通过第二二极管D2同时给第一电容C1充电。输出电容Cout给负载供电，以维持输出电压Vout不变。(2) In the (t 1 ~ t 2 ) stage, the modal diagram of the converter at this stage is as shown in Fig. 3b, the drive signal V GS of the switch S is changed from a high level to a low level, and the switch S is closed.

由于第一电感L1与第二电感L2的电感值相同，第一电容C1与第二电容C2的电容值相同，且是一个对称结构，故第一电感L1、第一电容C1分别与第二电感L2、第二电容C2的电压、电流相等。Since the inductance values of the first inductor L 1 and the second inductor L 2 are the same, the capacitance values of the first capacitor C 1 and the second capacitor C 2 are the same and are a symmetrical structure, so the first inductor L 1 and the first capacitor C 1 is equal to the voltage and current of the second inductor L 2 and the second capacitor C 2 , respectively.
由式(1)得到输入电压Vin与第一电容C1电压VC1的关系式(2)。The relationship (2) between the input voltage V in and the first capacitor C 1 voltage V C1 is obtained from the equation (1).
