Abstract: (47 Views) |
In this paper, an interleaved high-step-up converter with a new auxiliary circuit has been presented, so that the auxiliary circuit provides switching conditions at zero voltage for the main switches, and the auxiliary switch itself operates as switching at zero current. On the other hand, the auxiliary inductors are coupled with the main inductors and the energy of the auxiliary circuit is effectively transferred to the output. Due to the high gain of the converter, the voltage stress on the main switches is low. Also, due to the short time the auxiliary switch is on, the circulating current in the auxiliary circuit is not high and does not impose noticeable losses to the converter. Also, all converter switches have a grounded source, and there is no need for an isolated drive circuit. The proposed converter has been fully analyzed and to prove the circuit theory analysis, a sample of it has been simulated in PSPICE software.
