In order to utilize energy from low voltage power source it is necessary to use isolated DC/DC boost converter which will provide desirable input voltage step-up. To obtain a high voltage gain it is necessary to apply a magnetic device with the relevant turns ratio to the converter structure. This can be coupled inductor or transformer. The great advantage of the transformer is galvanic isolation...
The renewable energy sources or energy storage devices deliver output voltage at the range of around 12 VDCto 48 VDC. In order to obtain at least 350 VDCneeded for direct to alternating current conversion the DC/DC power converter should demonstrate significant voltage gain and power conversion efficiency as high as possible. To obtain such level of output voltage at low input voltages transistors...
