单相整流器快速动态响应控制策略研究
Research on Control Strategy with Fast Dynamic Response for Single-phase Converter
摘要
Abstract
In order to improve dynamic performance of single-phase PWM converter output voltage,a control strategy based on feedback of the capacitor energy storage and load power feedforward with coefficient correction was proposed through analyzing the inside power transitive relation of single-phase PWM converter. The output voltage overshoot was decreased by the feedback of the capacitor energy storage while load disturbance,meanwhile the load disturbance′s impact to the system was reduced by load power feed-forward with coefficient correction. According to the simulation,system′s output voltage overshoot was decreased from 12.5% to 5% ,dynamic regulating time was decreased 49 ms during the dynamicprocess,the proposed control strategy′s superiority is validated.关键词
