Experimental results validate the analysis. In addition, they are in good agreements with each other. There are several problems when it comes to achieve a high voltage gain with conventional DC-DC converters. The efficiency and operation quality of these converters are influenced by switching in high duty cycles. According to the voltage conversion ratio equations of conventional converters, they should convert input to a high voltage. However, problems like the inductor resistance effect, power loss and voltage drop on non-ideal components limit their operation in high duty cycles. Solving these problems requires new topologies based on conventional converters such as boost, buck-boost, SEPIC, Cuk and Zeta converters. To increase the boosting gain, new topologies have been presented. In some of them, the switching method between the inductors and capacitors have been changed. The others contain new methods such as the voltage-lift technique, which use multipliers and cascading as the second step of boosting the voltage. These topologies poses drawbacks that provide the motivations for proposing new structures. The main cause of these drawbacks is the base converter of multilevel systems. For example, using boost or SEPIC converters in a multilevel converter imposes voltage ripple on the output voltage -.īoost and buck-boost converters are conventional converters that have been frequently used in fuel cell systems and photovoltaic energy applications. In and, a hybrid boost and a double switch buck-boost converter are used for PV systems to increase the voltage gain and to extract the maximum power by the MPPT method. The authors of proposed a quadratic buck-boost converter with positive output voltage and a continuous input current. In addition, considers a soft switching method to decrease the switching losses in a boost converter. Some of these papers discus new techniques such as using interleaved converters to make the input current continuous. Using the interleaved method simultaneously reduces the output voltage ripple and the input current ripple. Furthermore, it improves voltage gain and efficiency. The negative point of using conventional boost and buck-boost converters in interleaved and multilevel structures is the fact that they produce spikes in the inductors current and output voltage, which can be seen in the experimental results. The Cuk converter is another conventional converter that can be studied for boosting applications. The Cuk converter is used in various kinds of applications such as MPPT systems and multi-output converters. Thus, it can be a candidate for connecting renewable source to loads. The Cuk conversion voltage ratio makes it an unsuitable choice for use as a boosting mode converter.
