摘要： The disclosure provides a bi-directional split-phase inverter circuit and a bi-directional split-phase inverter. The circuit includes a positive DC bus, a negative DC bus, first and second DC filter capacitor units, M AC filter capacitor units, M bi-directional switch networks, a neutral wire and M live wires. The circuit adopts the inverting coupling transformer for bi-directional power conversion, the switch bridge arm may realize a current loop, such that before a corresponding power switch transistor of the switch bridge arm turns on, its body diode is turned on first, thus reducing the reverse recovery power consumption of the body diode of the corresponding power switch transistor and realizing the zero voltage soft switching, and reducing the switch power consumption of the power switch transistor. The midpoint of the reinverting coupling transformer may provide multi-level output, further reducing the switch power consumption of the power switch transistor.

摘要： A multiphase inverter circuit and a modulation method thereof. The multiphase inverter circuit is configured for generating a target alternating current power based on a direct current power provided by a DC power supply, and the multiphase inverter circuit includes at least one non-interleaved inverter circuit; the non-interleaved inverter circuit includes: a first bridge arm unit, a second bridge arm unit, and an inverting coupling transformer. When the first pulse signal and the second pulse signal with a phase difference pass through the inverting coupling transformer, a current loop can be formed within the non-interleaved inverter circuit so that the body diodes of the power transistors conduct before the power transistors conduct, thereby reducing the reverse recovery power consumption of the body diode of the corresponding power transistor and realizing zero-voltage soft switching.

摘要： The present disclosure relates to a method and device for controlling vehicle air conditioner, and a vehicle on-board controller. The vehicle on-board controller acquires the target command, the target command is generated and sent by the terminal at the target time according to the target pre-control strategy. The target pre-control strategy is generated according to the key data and confirmed by the user. Therefore, the vehicle on-board controller can control the vehicle on-board battery to provide the target input power for the vehicle air conditioner within the preset length of time according to the target command, so that the vehicle air conditioner may precool or preheat for the preset length of time from the target time.

摘要： The present disclosure relates to a charging device. By providing a charge-enabled pin and an engage-enabled pin with different lengths in the charging interface of the charging device, the engage-enabled pin is firstly in contact with a battery when charging. At this time, a charging management circuit controls an LLC half-bridge resonant power supply to soft start. A third end of the charging management circuit outputs a signal to drive a first switch to be turned on, and the output end of the LLC half-bridge resonant power supply charges the battery, and charging soft start and zero-voltage connection are achieved. During the unplugging process, the charge-enabled pin is firstly removed from the battery, and zero-current disconnection can be achieved when unplugging the other pins of the charging interface.
