主 题：Three-winding coupled inductor voltage multiplier output diode stress high step-up
摘 要：A novel DC-DC converter topology that uses a three-winding coupled inductor(TWCI)and a new voltagemultiplication technique is presented for achieving high voltage gain.The proposed converter comprises one boost unit,one passive absorption circuit,and two voltage-multiplier cells.The tertiary winding of the coupled inductor is connected to a capacitor and diode,and this combination acts as a secondary voltage-multiplier cell(SVMC).The SVMC,when combined with two capacitors,the secondary winding of the coupled inductor,a diode,and a switch,forms a primary voltage-multiplier cell,which can achieve a large voltage-conversion ratio that can be adjusted easily.The new voltage-multiplier technique can be used to decrease the number of capacitors and diodes,which improves the transformation efficiency.A prototype circuit with a nominal rating of 300 W is designed to verify the correctness of theoretical analysis.
