An efficient controller design of a PV integrated single inductor multiple output DC–DC converter for dynamic voltage and low power applications

“…Reducing the number of switches by meeting power requirements is the main aspect of the proposed model. The proposed model has a smaller count of switching components compared with Jung et al, 30 Lee et al, 31 Shi et al, 35 Johari et al, 36 Güler and Irmak, 37 Zhang and Ma, 41 and Lee et al 52 The proposed controller has robust control operation with better settling time, response time, and less steady-state error compared with references Zheng et al, 28 Lee et al, 31 Waters et al, 34 Shi et al, 35 and Zhang and Ma. 41 The proposed control model efficiently tracks the peak current limit of the inductor current and switches the output channel under balanced and unbalanced loading conditions.…”

“…Specifically, the cross-voltage problem has been digitally controlled based on Model Predictive Control (MPC). Lee et al 31 proposed a dead-beat method by considering the regulation of source current and load terminal voltage. These two methods suffer less response time and complex mathematical calculations relatively.…”

Review of the Multi-Input Single-Inductor Multi-Output Energy Harvesting Interface Applied in Wearable Electronics

“…A delay-locked loop (DLL) is utilized in Chen et al, 2019a to accelerate the calibration. Lee et al, 2020a implemented the constant peak-inductor-current (CPIC) approach to fix the off-time under the same output voltage, where the on-time is adaptively changed with different input voltage to satisfy the voltage-second balance. Therefore the operation duration for the off-time calibration can be minimized thereby reducing the power consumption.…”

“…Homoplastically, The buck-based dual-control mode proposed in Kim et al (2021) charges the first output in indcuctor energizing phase and the second output in deenergizing phase, which also powers the two outputs in a single period resulting a reduced output voltage ripple. Other methods like 2-D AOT with APIC technique implemented in Lee et al, 2020a keeps a fixed ratio of ripple and output voltage values when the output voltage is changing, so as to reduce the output voltage ripple. Nagateja et al (2019) employed a H-bridge capacitor to combine the AC and DC source energy before subsequently pumping it up, which ensures a continuous inductor current that reduces output voltage ripple by 67%.…”
