Abstract

In this paper, a single-inductor dual-input dual-output (SIDIDO) power converter with sequential pulse-skip modulation (SPSM) is proposed for IoT applications. It manages power from a 1.4-V zinc-air battery and a 0.55-V to 0.7-V photovoltaic (PV) module to prolong the battery life. The proposed converter employs buck-boost mode and buck mode for PV module and the battery, respectively, to produce two different output voltages. The input sources are automatically selected by mode detection circuit which monitors both PV voltage and the output voltage to minimize the battery usage. The proposed SPSM along with a constant voltage maximum power point tracking (MPPT) method controls output voltages with low cross regulation while extracting the maximum power from a PV module. The measurement results demonstrate a peak efficiency of 89 % with an available input voltage of 0.55 V to 1.4 V.

一种用于电池/光伏混合系统的单电感双输入双输出(SIDIDO)时序脉冲跳变电源管理

本文提出了一种用于物联网应用的单电感双输入双输出(SIDIDO)时序跳脉冲调制(SPSM)功率转换器。它管理来自1.4 v锌空气电池和0.55 v至0.7 v光伏(PV)模块的电力，以延长电池寿命。所提出的变换器分别对光伏组件和电池采用降压模式和降压模式，产生两种不同的输出电压。输入电源由模式检测电路自动选择，该电路监测PV电压和输出电压，以尽量减少电池的使用。所提出的SPSM与恒压最大功率点跟踪(MPPT)方法一起以低交叉调节控制输出电压，同时从光伏组件中提取最大功率。测量结果表明，当输入电压为0.55 V至1.4 V时，峰值效率为89%。
