A power supply network, its multilevel circuit and a combined multilevel circuit

Abstract

The application discloses a multi-level circuit, including: a first circuit connected to a load or a power grid for providing a P level, and the first circuit is set at a first site; connected to a load or a power grid for providing a Q level Level of the second circuit, and the second circuit is set in the second site; wherein, P, Q are positive integers not less than 2; when the direction of the current flowing through the load or grid is the first direction, the current flows through the first The circuit and the load or the grid flow to the second circuit; when the direction of the current flowing through the load or the grid is the second direction, the current flows to the first circuit through the second circuit and the load or the grid. By applying the solution of the present application, wiring is facilitated on the premise that the level quantity requirement of the multilevel circuit is met. The application also provides a power supply network, which has corresponding technical effects. The present application also provides a combined multi-level circuit, which can provide 4 levels, 5 levels or 6 levels for the load or the grid to meet different requirements.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a power supply network, its multilevel circuit and a combined multilevel circuit. Background technique [0002] With the continuous development of the power industry, multi-level circuits are being used more and more widely. However, the number of levels provided by common multilevel circuits is limited, for example, it is common to provide multilevel circuits with 2 levels or 3 levels. In order to obtain more levels, for example, when 5 levels or 6 levels are required in practical applications, the circuit configuration is more complicated, which leads to complicated wiring. [0003] To sum up, how to facilitate wiring under the premise of meeting the level requirements for multi-level circuits is a technical problem urgently needed to be solved by those skilled in the art. Contents of the invention [0004] The purpose of the present invention is to provide a power ...
