A switching device includes a lower cover, an upper cover, a slider, at least one elastic element, and a high-impedance conductive plate. The lower cover is disposed on a circuit board. The upper cover is disposed on the lower cover. The upper and lower covers form an accommodating space. The slider passes through the upper cover and is configured to slide relative to the upper cover in one direction. At least one elastic element is located in the accommodating space. The high-impedance conductive plate is connected to one end of the at least one elastic element. The high-impedance conductive plate deforms upon receiving pressure from the slider. The deformation causes a change in the resistance value of the high-impedance conductive plate. The high-impedance conductive plate generates a switching signal in response to the deformation. The deformation is associated with the resistance value of the high-impedance conductive plate. The switching device of the present invention can generate a switching signal between a pressed state and a non-pressed state, thereby increasing the flexibility and possibilities of keyboard key applications in the e-sports field.

This invention discloses a commutation method for a modular multilevel converter in quasi-two-level mode, comprising: determining the commutation stage and output current polarity, identifying the delayed control object, and determining the operation mode based on the phase voltage level switching direction; directly executing the operation of the non-delayed control object according to the determined operation mode and constructing two candidate paths for the delayed control object: direct operation and delayed operation; calculating the circulating current prediction value and the absolute error with the reference value corresponding to the direct operation and delayed operation respectively, and determining whether the delayed control object should operate directly or delayed based on minimizing the error; introducing a piecewise linear trajectory synthesis fine-tuning mechanism based on duty cycle, determining the delay time of the bridge arm submodule by calculating the duty cycle, and repeating the steps until the commutation process ends; this invention quickly completes the commutation of the upper and lower bridge arms by adding a delay, and at the same time, the piecewise linear trajectory synthesis mechanism based on duty cycle eliminates the steady-state error caused by the whole-cycle delay.
