Stand Alone Voltage Mode Inverters

Posted by Dave Zendzian on Aug 19, 2013 9:33:00 AM

As previously discussed, most modern sine wave inverters employ a voltage source topology and are referred to as voltage source inverters (VSI).  Depending on the type of feedback and control scheme that is employed, the VSI topology can be used to implement inverter solutions for a wide variety of applications, including motor drives, grid-tie, and AFE/active rectifiers, as well as Voltage Mode Inverters (VMI).

VMI’s are also referred to as stand-alone or off-grid inverters. They are designed for remote stand-alone applications or off-grid power systems with battery backup where the inverter draws its DC power from batteries charged by some other power source, such as a PV array.  Applications for VMIs include solar home systems, rural electrification, and village electrification in remote areas where the utility grid is not available.
