As aviation power supply is developing to be increasingly integrated, by sharing the same main circuit, AC and DC dual output can be achieved through the same power supply to greatly improve power integration and power density. However, transformation ratio and transformer leakage in AC conversion can cause voltage drop in DC output and thus fail to meet the rated voltage of aviation DC power. To...
The sampling points in one cycle of 400 Hz inverter is 8 times less than that of 50 Hz inverter, resulting in lower control accuracy and larger static error in 400 Hz power supply system. According to the characteristics of the 400 Hz inverter, this paper establishes a mathematical model for single-phase solid-static power supply system. The changes in line impedance and load can be considered as...
