Embodiment 1

[0028] figure 1 A schematic structural diagram of a series-parallel heat switching system for a Hall electric propulsion anode power supply module proposed for an embodiment of the present invention; figure 2 It is a schematic diagram of the circuit output state of the switching process of the series-parallel thermal switching system of the Hall electric propulsion anode power module series-parallel thermal switching system provided by Embodiment 1 of the present invention. Taking four anode power modules as an example to realize the series-parallel thermal switching of modules, the same method can be used for the thermal switching of other numbers of anode power modules.

[0029] refer to figure 1 as well as figure 2 , if the initial state of the circuit is that the outputs of 4 anode power modules are connected in series, then the 4 anode power modules are all in the enabled state, that is, the switches KS1, KS2, KS3, and KS4 are all closed; at the same time, the switch ...

Abstract

The invention provides a Hall electric propulsion anode power supply module series-parallel heat switching system which comprises the components of an anode power supply module; an enabling switch which is connected with the anode power supply module; and a power switch tube array which is connected with the anode power supply module. The invention further provides a switching method of the Hall electric propulsion anode power supply module series-parallel heat switching system. According to the Hall electric propulsion anode power supply module series-parallel heat switching system, through combination of the power switch tube array which controls the series-parallel connecting form of the anode power supply module and the power tube switch array that controls power output of the anode power supply module, series-parallel heat switching of the Hall electric propulsion anode power supply module is realized.

Description

technical field [0001] The invention relates to the technical field of electric switching, in particular to a series-parallel heat switching system of Hall electric propulsion anode power supply modules and a switching method thereof. Background technique [0002] The electric propulsion system has the characteristics of high specific impulse. Under certain conditions, the spacecraft can obtain a speed increment of tens of kilometers per second, while traditional chemical propulsion is difficult to achieve this level. Taking a deep-space probe with a launch mass of 1500kg and an electric power of 3kW as an example, a dual-component chemical propulsion with a specific impulse of 315s is used. Even when the ratio of propellant consumption to launch mass is 0.8, the speed increment that can be provided is only 4.9km / s, while using high specific impulse electric propulsion technology, the speed increment can reach 20km / s. [0003] In addition, the use of electric propulsion sys...
