Abstract: A power supply device includes a power conversion circuit configured to generate an output voltage from an input voltage, and a controller coupled to the power conversion circuit and configured to control the power conversion circuit to generate the output voltage for causing or enhancing coalescence of a multi-phase liquid mixture when the output voltage is applied to the multi-phase liquid mixture. The controller is configured to control generation of the output voltage in accordance with a synchronization signal. The controller is further configured to generate the synchronization signal and transmit the synchronization signal to another power supply device, or receive the synchronization signal from another power supply device.

Abstract: A power supply device includes a power conversion circuit configured to convert an input voltage into an output voltage, a controller, and an output switch. The controller is coupled to the power conversion circuit and configured to control the power conversion circuit to generate the output voltage for causing electrical coalescence of a multi-phase liquid mixture when the output voltage is applied to the multi-phase liquid mixture. The output switch is coupled between an output of the power conversion circuit and a terminal of the power supply device. The output switch is switchable among a first position at which the output of the power conversion circuit is coupled to the terminal, a second position at which the output of the power conversion circuit is grounded, and a third position at which the output of the power conversion circuit is electrically isolated from the terminal and the ground.
