A resonant converter and a voltage conversion method. The resonant converter includes a high-frequency inversion circuit, an inductor-inductor-capacitor (LLC) resonant tank network, and a hybrid rectification circuit. The LLC resonant tank network is separately coupled to the high-frequency inversion circuit and the hybrid rectification circuit. The high-frequency inversion circuit is configured to convert a first direct current voltage into a first alternating current voltage. The LLC resonant tank network is configured to adjust the first alternating current voltage to obtain a second alternating current voltage.

Resonant converter and voltage conversion method

A current sampling system, the system including a magnetic component, that is an inductor or a transformer that has at least one winding, where the at least one winding has a first part and a second part, where a first terminal of the first part is connected to a first terminal of the second part, and where a second terminal of the first part is separated from a second terminal of the second part, and a current detection circuit, where the second terminal of the second part is connected to the current detection circuit, and where the current detection circuit is configured to sample a current flowing through the second part, and obtain a total current of the winding based on the sampled current flowing through the second part and a preset ratio.

A power distribution system includes a backplane communication busbar and a circuit breaker. The backplane communication busbar includes at least one slot, and a first interface is configured in each slot. Each first interface is connected to a first resistor Rhaving a different resistance value. A second interface of each circuit breaker is connected to a second resistor R, and when the second interface of the circuit breaker is plugged in any first interface, a preset voltage interval corresponding to a resistance value of the first resistor Ris uniquely determined by using a series circuit including the first resistor Rand the second resistor R

Circuit breaker identification method and apparatus, and device

An electrical connector includes an insulating housing having a longitudinal and a lateral wall defining a top face and at least one contact. The lateral wall defines a slot thereon. The contact includes a main body located one the top face of the lateral wall and a contacting arm located above the longitudinal wall, a connecting portion extending from an inner edge of the main body and a retaining portion extending from an outer edge of the main body. The retaining portion is retained and received in the slot. A pressed portion laterally extends from the main body.
