A variable frequency drive system including an alternating current electrical power source, an alternating current motor and a variable frequency drive connected to the power source and the motor. The variable frequency drive provides electrical power to the motor, and includes an active rectifier to convert a first alternating current from the power source to a direct current and an inverter to convert the direct current to a second alternating current. A variable frequency drive output voltage is greater than a variable frequency drive input voltage, compensating for the motor apparent current. A method of electrical power conversion includes urging a first alternating current from a power source to a variable frequency drive. The first alternating current is converted to direct current via an active rectifier of the variable frequency drive, and the direct current is converted to a second alternating current via an inverter of the variable frequency drive. |
