Abstract: A method includes detecting a voltage signal of a three-level power converter, the voltage signal indicative of a capacitor voltage balancing in the three-level power converter, and dynamically adjusting an operating variable to adjust the voltage signal until the capacitor voltage balancing in the three-level power converter satisfies a criteria.

Abstract: A bidirectional power conversion system includes an isolated power converter having a first input connected to an output of a diode rectifier and a second input connected to an output of a power factor correction device. The power conversion system further comprises a plurality of switches and a plurality of diodes configured such that the plurality of switches and the plurality of diodes form the diode rectifier and the power factor correction device when the system is configured to deliver power from an AC power source to a DC load and the plurality of switches forms an inverter when the system is configured to deliver power from a DC power source to an AC load.

Abstract: A system includes a first power conversion device connected to a first power source, a first isolated power conversion device connected to the first power source, and a second power conversion device connected to the first isolated power conversion device, wherein outputs of the first power conversion device and outputs of the second power conversion device are connected in series, and series-connected outputs of the first power conversion device and the second power conversion device are configured to drive a motor.

Abstract: A faucet comprises a faucet body, a water outlet mechanism, and a switch mechanism. The faucet body comprises a pull-out water outlet head and a pull-out pipe connected to the pull-out water outlet head, and the faucet body comprises a water outlet seat. The water outlet mechanism is rotatably connected to the water outlet seat, and the water outlet mechanism is configured to rotate. The switch mechanism comprises a valve member and a connecting pipe connected to the water outlet seat and the valve member to be in communication with the water outlet mechanism. The pull-out pipe is connected to the pull-out water outlet head and the valve member, and the pull-out pipe is configured to pass through and slide in a pull-out channel. The valve member is configured to control a connection between an external water source and at least one of the connecting pipe or the pull-out pipe.

Abstract: A faucet comprises a faucet body, a water outlet panel, and a panel water outlet pipe. The water outlet panel is configured to be arranged separately from the faucet body, and a valve seat comprises a water passage respectively connected to a first valve and a second valve. The first valve is in communication with hot water and cold water to form mixed water that is in communication with the water passage, and the second valve is configured to receive the mixed water and is configure to be controlled to enable the mixed water to be in communication with the water outlet panel. The faucet body comprises a water outlet terminal, the water outlet panel comprises a water outlet port, and the first valve is configured to be controlled to enable the mixed water to be in communication with the water outlet terminal.

Abstract: A water outlet panel assembly configured to be connected to a pull-out faucet comprises a water outlet panel, an adapter member, and a control member. The water outlet panel is detachably connected to a faucet body of the pull-out faucet, and the water outlet panel comprises a water outlet port. The adapter member comprises a water inlet, a first water outlet, and a second water outlet, and the water inlet and the first water outlet are detachably connected to a pull-out pipe of the pull-out faucet.
