摘要： A method and apparatus for controlling an inverter includes operating the inverter in a one of a normal run mode or a pulse mode depending on one or more criteria. When operating in the pulse mode, the inverter generates a sinusoidal output pulse waveform including a plurality of pulses having a determined pulse width. The pulse width is less than a half-wave period of a full-cycle sinusoidal waveform and may be determined as function of, for example, the output power of the inverter, a grid voltage, and/or other criteria.

摘要： An apparatus to deliver an alternating current (AC) power may include a controller having a processor and a memory. The apparatus may also include a plurality of power inverters in communication with the controller. Each power inverter may be configured to convert direct-current (DC) power into the (AC) power. Each of the plurality of power inverters may be configured to be controlled by the controller to generate AC power below at least one predetermined operating threshold. The plurality of power inverters may be configured to combine AC power generated by each of the plurality of power inverters, such that the combined AC power is delivered to a common AC load above the predetermined operating threshold. The apparatus may be arranged and operated according to a ratio of FMA=Fr/N, where Fr=fs/fl, fs is the switching frequency of the plurality of power inverters, fl is the frequency of the common AC load, and N is the number of power inverters of the apparatus.

摘要： A startup circuit for starting a power converter for converting an input voltage to an output voltage includes a switch connected in series with a resistive element. The startup circuit is connected in parallel with a trigger switch in the power converter for enabling the power converter to generate the output voltage. When closed or activated, the switch in the startup circuit charges an energy storing device in the power converter. The energy storing device activates the trigger switch as the charge is released.
