Some embodiments provide a UPS including a non-current-commutated solid-state bypass switch. The bypass switch may include at least one transistor configured to control current to the load. Further embodiments provide a UPS including a converter including a first half-bridge circuit having an input port configured to be coupled to an AC source and an output port coupled to first and second buses and a second half-bridge circuit having an output port configured to be coupled to a load and an input port coupled to the first and second buses. The UPS further includes a control circuit configured to control the converter to provide a first mode wherein the first bridge circuit and the second bridge circuit operate as a rectifier and an inverter, respectively, and a second mode wherein the first and second bridge circuits operate as a pass-through switch from the AC source to the load.
An uninterruptible power supply (UPS) comprising:
A UPS comprising:
A method of operating a UPS comprising a converter comprising a first half-bridge circuit having an input port configured to be coupled to an AC source and an output port coupled to first and second buses and a second half-bridge circuit having an output port configured to be coupled to a load and an input port coupled to the first and second buses, the method comprising:
