摘要： The present disclosure provides a control method of a DC/DC converter and a related DC/DC converter. The control method allows for: detecting a difference between a first voltage and a second voltage; if an absolute value of the difference between the first voltage and the second voltage is greater than or equal to a preset value, reselecting desired operating states of respective switches in a 1-level state according to the difference between the first voltage and the second voltage and a direction of an average current from a fourth node to a first passive network in the 1-level state; and thus outputting a control signal to enable the voltage difference between the first capacitor and the second capacitor to be reduced, thereby effectively adjusting the neutral-point voltage balance of the DC/DC converter.

摘要： The present disclosure provides a power supply system method for an AC load (10). The system includes a power supply device (11, 21, 31A, 31B, 41) and a DC/AC converter (12, 22, 32, 42). An AC side of the DC/AC converter is coupled to an AC grid (9) and the AC load through an AC bus (8). The power supply device outputs DC electric energy and is coupled to a DC side of the DC/AC converter through a DC bus (13, 23, 33, 43). The power supply device includes an energy storage circuit (111, 211, 311, 411) and a controller (112, 212, 312, 412). The energy storage circuit includes a first energy storage circuitry (1111, 2111, 3111, 4111) and a second energy storage circuitry (1112, 2112, 3112, 4112).

摘要： A voltage balance control method for a flying-capacitor multilevel converter (1) is provided. If the amplitude of the resultant current of the inductor currents from a plurality of output inductors (Lf) is lower than or equal to a threshold current value, the flowing direction of the inductor current of at least one flying-capacitor multilevel branch circuit (10) is controlled to be changed. Consequently, the problem of erroneously judging the current direction is avoided. Moreover, when the inductor current is low, the voltage of the flying capacitor (C1, C2) is correspondingly controlled. Consequently, the voltage balance of the flying capacitor (C1, C2) of the flying-capacitor multilevel converter (1) can be achieved more easily.

摘要： A housing covering an electronic component is provided. The housing includes a body, a first coupling portion, and a third coupling portion. The body has a first surface and a second surface connected to the first surface, and a normal direction of the first surface and a normal direction of the second surface are interlaced with each other. The first coupling portion is disposed on the first surface and detachably coupled with a second coupling portion of a terminal of the electronic component, such that degrees of freedom in a first direction and a second direction of the terminal are restricted. The third coupling portion is disposed on the second surface and detachably coupled with a fourth coupling portion of the terminal, such that a degree of freedom in a third direction of the terminal is restricted. The first direction, the second direction, and the third direction are linearly independent.
