Abstract

A power system includes a plurality of DC/DC converters and a DC/AC inverter. The plurality of DC/DC converters having outputs electrically connected in parallel for supplying a DC voltage bus to an input of the DC/AC inverter. The plurality of DC/DC converters each include a maximum power point tracker (MPPT). Various DC/DC converters and DC/AC inverters suitable for use in this system and others are also disclosed.

Claims

exact text as granted — not AI-modified
1 - 4 . (canceled) 
     
     
         5 . A DC/DC converter having an input, an output, at least one power switch coupled between the input and the output, and a controller having a maximum power point tracker (MPPT), the controller configured to run its MPPT when the output voltage of the DC/DC converter is pulled below a first voltage. 
     
     
         6 . The DC/DC converter of  claim 5  wherein the controller is configured to regulate its output voltage until the output voltage is pulled below the first voltage. 
     
     
         7 . The DC/DC converter of  claim 5  wherein the controller is configured to stop running its MPPT when the output voltage rises to the first voltage. 
     
     
         8 . The DC/DC converter of  claim 5  wherein the controller is configured to stop running its MPPT when the output voltage reaches a second voltage lower than the first voltage. 
     
     
         9 - 17 . (canceled)
