Active power conditioner system
A system is described for power conditioning a line of supply of AC power from an AC source to an AC load, comprising: a first array of static power switches mounted across one AC source and AC load; a second array of static power switches coupled in series with the AC supply line; a DC source connected between the first and second arrays; first controlling means operative upon the first array in one of two modes to effect conversion between one of the AC source and AC load on one side and the DC source on the other side; second controlling means operative upon the second array in one of two modes to effect conversion between the DC source on one side and the AC supply line on the other side; the first array operating as a rectifier when the second array operates an an inverter, and the first array operating as an inverter when the second array operates as a rectifier; whereby the first and second controlling means provide one of a buck and boost voltage on the AC supply line while maintaining the DC source constant.
