“…The conventional dc-dc converters consist of different voltage gains in different duty cycles (D) [3][4][5][6], but because of limitation in converter's parameters, the value of (D) could not be selected higher than specific value [7,8]. In [7,8] the stability analysis were done for the conventional boost dc-dc converter. Based on mentioned in [7,8], the variation of D is restricted, and it cannot increase to maximum values.…”

“…High output voltage, same polarities with input voltage source and high efficiency are some of the advantages of the proposed boost dc–dc converter, and because of these specific features it could be used in electrical systems. The conventional dc–dc converters consist of different voltage gains in different duty cycles ( D ) , but because of limitation in converter's parameters, the value of ( D ) could not be selected higher than specific value . In the stability analysis were done for the conventional boost dc–dc converter.…”

“…In the stability analysis were done for the conventional boost dc–dc converter. Based on mentioned in , the variation of D is restricted, and it cannot increase to maximum values. Therefore, the output voltage gain is limited, and it is impossible to use of these converters in high voltage gain applications such as vehicle devices.…”

In this paper, a new boost dc-dc converter based on voltage lift (VL) technique is proposed. There is any need for transformer, coupled inductances and sequential connections in the proposed boost converter topology. In this paper, the operating of proposed boost dc-dc converter in continuous conduction mode (CCM) and discontinuous conduction mode (DCM) was discussed, and the current and voltage equations of the inductors and capacitors were obtained with details. So, the value of critical inductance and the operating of the proposed dc-dc converter between CCM and DCM were presented. The switching currents of each switch were analyzed. The switches, diodes, inductors and capacitors root-mean-square (RMS) current stresses were discussed. Finally, the correct performance of the proposed converter based on presented theoretical issues is verified by using simulation results on EMTDC/PSCAD software program and experimental results by using laboratory prototype.

“…So, the proposed method is a complete method for analyzing DC-DC converters. In addition, the proposed method can be used to design a suitable controller to improve converter stability [23,24]. In addition, it can be used to design the values of converter elements to achieve the minimum values of output voltage and inductor current ripples.…”
