Abstract: A method, apparatus, and system to control and test a solar inverter are provided. The method commissions a solar inverter of a solar plant before it is placed into power production. The commissioning process verifies that the inverter to be tested is functioning as intended by connecting a first inverter to the inverter to be commissioned, and using the first inverter to emulate the power grid without being connected to the power grid, and circulate reactive and limited active power between the first inverter and the inverter to be commissioned.

Abstract: A precharging circuit for precharging an intermediate circuit capacitor of a converter formed from at least one electrolytic capacitor using a grid current from a supply grid before the converter is connected to the supply grid and is used for the reformation of at least one electrolytic capacitor of the intermediate circuit capacitor. A method is provided for the reformation of an intermediate circuit capacitor of a converter formed from at least one electrolytic capacitor, which is connected to the supply grid using a precharging circuit. A converter is created for converting an AC grid voltage into a direct voltage or vice versa, with a device for the reformation of electrolytic capacitors of an intermediate circuit capacitor of the converter using an integrated precharging circuit of the converter. Existing hardware can be used for the reformation of electrolytic capacitors in a converter, and the expense associated with the reformation can be minimized.

Abstract: A DC/DC power converter connected to a DC power source/load having first and second DC terminals. The DC/DC power converter operates in voltage step-up and step-down modes. The converter includes first and second DC buses connected to the first and second DC terminals and third and fourth DC buses defining a DC link. Energy storage devices are connected between the third and fourth buses. A first converter leg includes a first branch with switches and a second branch. Each switch includes a controllable semiconductor switch and an anti-parallel connected freewheeling diode. A controller switches the controllable semiconductor switches between a conducting and non-conducting state, in the step-up and step-down modes, switching to supply power from the DC power source/load to the DC link in the step-up mode and to supply power from the DC link to the DC power source/load in the step-down mode.
