| The wind plant captures and transforms wind energy into direct current electricity. |
| The inverter changes the solar direct current into the alternating current used by most household appliances. |
| An integral inverter changes the direct current to alternating current for transmission into the facility's electrical distribution systems. |
| Its one-directional conduction gave it the ability to convert alternating current into direct current. |
| They connect only through tie lines where power must be converted from alternating current to direct current and back again. |
| A circuit arrangement for supplying a discharge lamp with a direct current includes input terminals for connection to a supply voltage source. |
