    Abstract: 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.

    Abstract: In described examples, a Phase Regulated Power Supply includes a low output DC logic power supply, a voltage divider to sample the input AC waveform, one or more comparators, digital logic, and a switching transistor. It can include a Full Wave Rectifier and one or more capacitors, inductors and opto-isolators. In the most basic form, Alternating Current (AC) power is switched directly to a load when the AC instantaneous voltage is between a low and high set-point. Voltage is regulated by controlling the high set-point. Current through the load is regulated by briefly extinguishing the AC input from the load when the load current exceeds a set parameter. Voltage output to the load is adjustable from zero volts to the AC peak voltage. Current through the load is adjustable from zero amps to the AC circuit breaker limit.

    Abstract: A technology is disclosed for controlling switching of power converters included in a power converting system. Phase angles are allocated to a plurality of sub-units corresponding to the power converters, and the respective sub-units create local switching carriers based on the allocated phase angles. The sub-units compare a reference AC voltage with the local switching carriers, and switch the power converters according to the result of the comparison.

    Abstract: A command device is connected with a serial line to a driving device for controlling operations of a plurality of first switching elements and one or more second switching elements. The command device includes a command signal generator to generate a plurality of first command signals and one or more second command signals, an encoder to generate encoded data by encoding at least some signals of the plurality of first command signals and the one or more second command signals, and a command-device serializer to generate serial command data through serial conversion of the encoded data and transmit the serial command data to the driving device via the serial line.
