Abstract

Embodiments of the present invention relate to a control method and a control apparatus. The control method and apparatus are applied to a BUCK-BOOST topology. The method specifically is, processing an output signal of a topology to obtain a pulse width modulation signal, performing an OR operation between the pulse width modulation signal and a first modulation signal to obtain a first control signal so as to control a state of a first transistor on the topology, and performing an AND operation between the pulse width modulation signal and a second modulation signal to obtain a second control signal so as to control a state of a second transistor on the topology. Therefore, the method achieves three topology states and a smooth switchover among the three topology states. In addition, the control circuit is relatively simple, expanding the control scope and improving the control precision.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a control method and device. Background technique [0002] With the increase of the power of routers, enterprise network equipment and single boards, some high-power frame equipment requires the DC / DC (Direct Current / Direct Current, DC / DC) voltage regulation module in the system to support flexible configuration, so as to be used for Satisfy the customer's investment requirements and the power distribution requirements of the computer room. In order to improve the conversion efficiency of the DC / DC voltage regulator module, a single-inductor buck-boost (BUCK-BOOST) topology is a topology that supports the DC / DC voltage regulator module to achieve high efficiency. [0003] figure 1 It is a circuit diagram of a single inductor BUCK-BOOST topology in the prior art. Such as figure 1 As shown, Metal-Oxide-Semiconductor Field-Effect Transistor (Metal-Oxide-Semiconduc...
