Electrical power regulator |
摘要 |
Electrical power apparatus is disclosed for selectively powering either a three-phase ac motor or a single-phase ac motor. A dc/ac inverter is configured to provide appropriately phased input signals to the three input terminals of whichever motor is being driven, with no substantial hardware reconfiguration being required. In addition, a special clamp circuit prevents an excessively high voltage from being applied to the inverter by a variable-voltage power source such as a photovoltaic array, whereby the inverter need not be sized to accommodate voltage levels substantially greater than its design voltage.
