SolarBridge Technologies | Date: 2011-04-27

A method for controlling an multi-stage inverter comprises controlling an input converter of the multi-stage inverter with an input controller and controlling an output converter of the multi-stage inverter with an output controller separate from the input controller. The input controller and output controller may be galvanically isolated. Additionally, the method may include communicating data between the input controller and the output controller over a power bus of the multi-stage inverter.

Reverse recovery avoidance when converting power is provided. A first switch and second switch may be operated to supply an AC load with positive current, respective to the AC load, from a DC power source. A third and fourth switch may be operated to supply the AC load with negative current, respective to the AC load, from the DC power source. Four diodes may be employed with the switches. One diode may conduct the positive current when the first switch is off and the second switch is on. Another diode may conduct the negative current when the third switch is off and the fourth switch is on.

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.

Processes, machines, and articles of manufacture that may serve to enable the detection or determination of alternating line voltages from an alternating power source, such as the power grid, are provided. This automatic sensing may be useful when connections are made to the power grid, such that when connections are made, the connections may be configured to be compatible with the available power source. This automatic sensing may also be useful if power sources change characteristics over time or if devices may be connected to different power sources over time.

A power inverter may include a transformer serving as an isolation barrier. The power inverter may include a first controller on one side of the isolation barrier. The first controller may encode the frequency of an input voltage of the transformer with one or more operating conditions of a direct current power supply electrically coupled to the inverter. As second controller on the other side of the isolation barrier may determine a frequency associated with an output voltage of the transformer. The second controller may decode the frequency associated with the output voltage of the transformer to determine the encoded operating conditions.
