【 摘 要 】

A novel power converter based on dual-transistor forward converter topology is proposed to meet the requirements of high power transmission between spacecrafts. Compared with the traditional two-transistor forward converter, this converter eliminates the secondary filter inductance and the diode of the rectifier. Theoretical analysis and experimental results show that the new topology reduces the use of magnetic elements, improves the power density of the converter, and improves the parasitic oscillation and reverse recovery of the rectifier diode. The new topology can better meet the requirements of power supply system for high reliability, reducing device stress, increasing the availability of key devices, optimizing system structure and so on.
