摘要:

为满足井下防爆场景下锂离子动力电池安全高效充电需求,设计防爆型智能充电器系统。主电路采用高频碳化硅(SiC)的单相H桥逆变器、超微晶铁芯高频变压器及快速整流桥,构建交-直-交1-交2-直(AC-DC-AC1-AC2-DC)多级隔离变换拓扑;以数字信号处理器(DSP) TMS320F28335为控制核心,采用恒流-恒压(CC-CV)双闭环比例-积分(PI)控制算法,实现多输入电压制式自适应、宽范围直流输出及多规格电池组自动适配。结果表明:该系统实现了CC至CV充电的平滑无冲击过渡,整体电能转换效率达94%以上,输出电压调节误差小于±0.5%,输出纹波系数低于1%,保护功能可靠,各项性能指标满足煤矿井下应用的要求。

Abstract:

In order to meet the requirements for safe and efficient charging of lithium-ion power batteries in explosion-proof underground environments, an explosion-proof intelligent charger system was designed. The main circuit employed a high-frequency silicon carbide (SiC) single-phase H-bridge inverter, an ultrafine crystalline iron core high-frequency transformer, and a fast rectifier bridge to form a multi-stage isolated alternating current-direct current-alternating current 1-alternating current 2-direct current (AC-DC-AC1-AC2-DC) converter topology. Centered on the TMS320F28335 digital signal processor (DSP), the system adopted a CC-CV double closed-loop proportional-integral (PI) control algorithm for adaptive operation across multiple input voltage modes, wide-range DC output, and automatic compatibility with various battery pack specifications. The results show that the system achieved a smooth, non-impact transition from CC to CV charging, with overall energy conversion efficiency exceeding 94%, output voltage regulation error less than ±0.5%, and output ripple coefficient below 1%, implementing reliable protection functions. All performance indicators meet the requirements for underground coal mine applications.

Key words: coal mine electric vehicle, explosion-proof intelligent charger, constant current-constant voltage (CC-CV), double closed-loop control, high-frequency transformer
