Problems solved by technology

For example, as a strategy for B1 to transfer energy to B3, the controller must decompose the strategy into: first B1 transfers energy to B2, then B2 transfers energy to B3; the gradual transfer of energy reduces the equilibrium speed of the entire equilibrium network, Due to the loss of equalization energy delivered by each stage, the equalization efficiency is low

Abstract

The invention discloses an isolation type equalization circuit based on a bus type equalization network. One end of a first inductor is connected with the positive pole of an input power supply, the other end of the first inductor is connected with a first power switch drain electrode, one end of a second inductor is connected with the negative pole of the input power supply, the other end of the second inductor is connected with a first power switch source electrode, one end of a third inductor is connected with a second power switch source electrode, the other end of the third inductor is connected with one end of a second capacitor, one end of a fourth inductor is connected with a second power switch drain electrode, and the other end of the fourth inductor is connected with the other end of the second capacitor. One end of a first capacitor a is connected with the first power switch drain electrode, the other end of the first capacitor a is connected with the second power switch source electrode, one end of a first capacitor b is connected with the first power switch source electrode, and the other end of the first capacitor b is connected with the second power switch drain electrode.

Description

technical field [0001] The invention relates to the field of automatic control, in particular to an isolated equalization circuit based on a bus equalization network. Background technique [0002] The equalization circuit is mainly divided into dissipative and non-dissipative. The dissipative type consumes all the excess energy on the resistor, which has low efficiency. The non-dissipative type transfers excess energy through the circuit and has high efficiency. Buck-boost is a typical cascaded equalization circuit, and its network structure is as follows: Figure 8 It is a cascaded balanced network based on buck-boost. The structure of the cascaded balanced network is relatively simple, but it has an obvious disadvantage: energy can only be transferred step by step. For example, as a strategy for B1 to transfer energy to B3, the controller must decompose the strategy into: first B1 transfers energy to B2, then B2 transfers energy to B3; the gradual transfer of energy reduce...
