摘要：

Aiming at the demand of high-gain DC/ DC converter in photovoltaic power generation system and fuel cell power generation system, two-phase interleaved parallel boost converter was taken as the research object, and an intersected voltage multiplier cell with the combination of two voltage multiplier cells containing inductors was designed, which can increase the voltage. According to this, a new high-gain DC/ DC converter with intersected voltage multiplier was proposed. This converter can achieve (3n +4) / (1 - d) times high voltage gain (1∶ n is the turn ratio of coupled inductor, d is the duty ratio of converter), and it has low voltage stress characteristics. To solve the problem of voltage spike caused by leakage inductance, clamping capacitor was introduced to form leakage inductance energy channel and increase the output voltage. The topology of the new high-gain DC/ DC converter with intersected voltage multiplier was proposed, the working process of each mode was analyzed, and the steady-state characteristics of voltage gain, input current ripple and voltage stress of each device were deduced. What’s more, an experimental prototype was built to verify feasibility and advance of DC/ DC conversion technology. © 2024 Editorial Department of Electric Machines and Control. All rights reserved.
