As current control algorithm, a linear current control algorithm which consists of a proportional-integral (PI) technique for steady state error control, with pulse width modulation (PWM) for producing switching signals for power switching devices, is chosen because its simplicity and easy ...
The grid-tied inverter plays a vital role in the energy conversion and control of the PV (photovoltaic) system [1]. With the proliferation of grid-tied PV generation and other distributed generation, the contribution which such generation can make to grid stability has come into sharp focus. ...

Furthermore, it only occupies a silicon area of 1.3 mm2. The proposed buck converter is dedicated for smartphone applications whereby it spends most of its time in idle, low load conditions. Keywords: DC-DC converter; twin frequency control; load sensing; buck converter; smartphone application ...
While the asynchronous sine-triangle PWM is a popular technique to modulate current error, it requires a PI (Proportional-Integral) regulator and often results in unavoidable delays. The predictive dead-beat control technique tends to give good performance in terms of response and accuracy. However,...

Zou et al. [15] studied the behavior of CapMix cells under different operating modes, but the extraction of energy from the cell was always done by direct connection to an external resistance. The value selected for this resistance affects the current and voltage in the cell, thus ...
