Embodiment Construction

[0022] Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0023] figure 1 A schematic structural block diagram of a hybrid inverter for converting direct current into alternating current according to the present invention is shown. refer to figure 1 , the hybrid inverter at least includes a DC conversion array 102 , a DC / AC converter 104 and transmission wires electrically connected between the DC conversion array 102 and the DC / AC converter 104 . Wherein, each row and each row of the array 102 have a plurality of DC-DC modules, for example, the first row to the fifth row all have three DC-DC modules, and the first column to the fifth column all have five DC-DC modules. modules, and two DC-DC modules adjacent to each other in the first row are electrically connected, that is, module 11 is connected to module 21, and module 21 is connected to module 31. At the same time, two adjacent DC-DC modules in...

Abstract

The invention provides a hybrid inverter for conversion of DC current into AC current, which comprises a DC conversion array, a DC / AC converter and a transmission line. Each line and each row of the DC conversion array is provided with a plurality of DC-DC modules; the DC / AC converter is used for conversion DC current into AC current; the transmission line is electrically connected between the array and the DC / AC converter. The DC-DC modules in each row of the array are electrically connected with the electrical input ends of a plurality of kinds of renewable energy respectively. The hybrid inverter can generate the expected DC capacity through onsite custom setting of the connection of the subunits, thereby realizing the effect of 'hybrid input and single output'. When one renewable energy device fails, the normal operation of other renewable energy devices can not be affected, thereby reducing the maintenance cost of the whole inverter, and greatly improving the adaptability of the inverter in different environments.

Description

technical field [0001] The invention relates to the application field of power electronics technology, in particular to the circuit structure design of a hybrid inverter in the power electronics technology. Background technique [0002] As we all know, an inverter is also called an inverter power supply. It is a power conversion device used to convert direct current into alternating current with stable output voltage and frequency. In this sense, an inverter is also a DC / AC (Direct Current / Alternating Current, DC / AC) converter. Using inverters, users can convert DC power (such as batteries, switching power supplies and fuel cells, etc.) into AC power to provide stable and reliable AC power for mobile power sites or areas without electricity. In addition, inverters can also be used in conjunction with generators to effectively save fuel and reduce noise, especially in the fields of renewable energy such as wind power and solar power, inverters are essential. [0003] For ex...
