用于电池化成的单相双向PWM整流器设计
Design of single-phase bi-directional PWM rectifier for battery formation system
摘要
Abstract
In order to reduce the energy waste during battery formation process, a single-phase bi-directional PWM rectifier device was designed for a novel high-efficiency and energy-saving formation system. The device was based on Freescale56F803 DSP control chip and adopted single-cycle control and digital Pl algorithm. A stable DC bus voltage control strategy was Proposed to achieve bi-directional transmission of energy between the grid and the bus The single-cycle PWM rectifier under the control of the work and characteristics of dead time was described in detail.the duty saturation occurred when PWM was operated under low bus voltage was analyzed, and the relevant solution was proposed. A 3 kW single-phase bi-directional PWM prototype works well in the battery formation system, and venrifies the feasibility of the design process关键词
