چکیده
Voltage lift is a well-known technique to improve the voltage gain of converter. A combination switched inductor and conventional can be used achieve high gain, but semiconductor's stress still high. An improved by employing an extra diode capacitor proposed, which significantly increases boosting factor reduces semiconductor devices. The proposed converter transformerless non-isolated in nature. topology has continuous input source current common connection between load. controlled single switch, making it simple use. steady-state relations are drawn out both conduction mode (CCM) discontinuous (DCM). effect unequal inductance on carried detail. develop n-stage further reduce semiconductors. compared with recent converters, non-idealities losses occurring components discussed hardware prototype rating 20V/300V, 250 W built test suggested topology's performance theoretical analysis. At 20-V input, highest efficiency was measured 95.8%.
