Embodiment 1
[0048] Such as figure 1 As shown, a modular satellite electric propulsion device with adjustable discharge pulse includes a power conversion module 1 , an energy storage and discharge module 2 , a pulse control module 3 , a switch drive module 4 , a thruster module 5 and a power module 6 .
[0049] Wherein, the power conversion module 1 includes a power converter 11 of an energy storage module, a power converter 12 of a switch driving module, and a power converter 13 of a pulse control module. The power conversion module 11 has functions of current limiting protection and surge suppression.
[0050] The energy storage and discharge module 2 includes a capacitor 21, an inductor 22, a controllable switch 23, a resistor 24, and the like. Using the principle that the current of the inductor 23 cannot change abruptly, an instantaneous increase in voltage is obtained. The power supply module 6 will charge the capacitor 21 when the power supply module 6 is powered on. When the cont...
