Abstract

With the increasing demand for stable and highly efficient power supply in electronics systems, voltage stability and ripple suppression have gained more significance. For optimization in conventional topology, traditional topology is not able to balance the response speed and the accuracy and increasing switch frequency raises switching losses. The four-switch Buck-Boost converter possesses many advantages, such as a simple structure, a wide range of input and output voltage, and bidirectional voltage conversion. This paper utilizes a four-switch Buck-Boost converter with PID control and proposes an integrated multi-optimization method to help solve the conflict between voltage accuracy and ripple performance. Based on the topology of the four-switch Buck-Boost converter, this paper builds a mathematics model of the circuit and simulation model. After comparing multiple groups of data, the optimal inductor value and equivalent series resistance (ESR) under the given conditions are 470μH and 0.01Ω respectively. The ripple coefficient is reduced to 4.7%, and the efficiency reaches 85%, meeting the design requirements. This paper provides electric vehicles, and renewable energy systems with theoretical and practical optimization of voltage stability and ripple suppression.
