“…The control scheme selected is the current-injected control (CIC) [6], [8]. By means of this control it is possible to control the peak of the current in the inductor or in the power transistor, which allows a protection, against overcurrent, inherent to the control.…”

This paper presents the modelling, design and implementation of a DC-DC converter integrated into a two-stage photovoltaic microinverter operating in grid connected mode. A push-pull topology has been chosen because it provides galvanic insulation and adjusts the DC voltage from the photovoltaic panel to an appropriate voltage with the implementation of a current-injected control (CIC). The push-pull electrical design is presented for a power of 200 W and an output voltage of 380 VDC. Also, the small signal model is presented, and the required transfer functions have been derived in order to design and implement the controllers that regulate the output current (detection of the peak current in the inductor) and the input voltage (PI controller) fixed by the reference imposed by a MPPT algorithm. Finally, the experimental results and conclusions are presented.

“…In applications such as conveyor belts, the induction motors usually operate at a constant speed and hence, a closed loop buck converter feeding an inverter can really help the motor (connected as a load to the inverter) to maintain specific speed. A complete study of current and voltage mode control of DC/DC converters is presented in [11] and its implementation using FPGA is presented in [12].…”

Power electronic converters play a vital role in a power system and the most commonly used type of DC/DC converters is buck converter. This is due to the fact that buck converters are widely used to step down the voltage as well as they provide good voltage regulation in critical applications including power supplies for data centers. Therefore, designing a buck converter that gives a regulated output, acceptable for switch mode power supplies is still challenging task. A closed loop buck converter mitigates the problems such as input voltage unstability or variation. This paper discusses the effects of input voltage variations on the open loop and closed loop models of buck converter. VoltageMode Control (VMC) has been proposed to develop an efficient closed loop system in order to avoid voltage fluctuations at the output of the buck converter.

This work aims to present an High Voltage High Power and High Frequency CMOS DC-DC converter able to work in both Flyback and Boost configurations, designed for automotive applications. The system, implemented in Austriamicrosystems 0.35um HVCMOS technology, is able to manage input voltages from 2.5V up to 36V and generates a programmable output voltage from 6 to 36V with an output current up to 900mA. To improve EMC/EMI system performances, dithering of switching frequency and slope controlling of the gate driver have been implemented.
