specific Embodiment

[0054] (1) UAV power supply module

[0055] The input of the UAV power supply module is 220V AC, and the output is 28.5V±0.5% DC. The ripple voltage of the UAV power supply module is V P-P The value is less than 100mV, and the rated output power is 5kW.

[0056] Such as figure 2 As shown, the 220V AC passes through the line filter to filter out the interference in the power grid, and then becomes an unstable DC after a rectification and a filter. The full-bridge soft switching conversion circuit is controlled by the CPU and the control board to convert the DC into a high-frequency AC, and then output stable DC through high-frequency transformer isolation, secondary rectification and secondary filtering circuit. The power factor improvement circuit inside the module is used to improve the power factor at the input of the power supply module.

[0057] The control circuit uses the CPU board of MSP430F149 as the core. The CPU board collects the output voltage and output curren...
