System and method for controlling a motor

A method of controlling an interleaved bridgeless power factor correction (PFC) converter-based motor drive system that includes a first inductor coupled to a second inductor, the coupled first and second inductors coupled to a first AC power supply line, and a third inductor coupled to a fourth inductor, the coupled third and fourth inductors coupled to a second AC power supply line, said method comprising:

• receiving, by a digital active PFC controller, a measured value of at least one operating parameter of the interleaved bridgeless PFC converter-based motor drive system;
• determining, by the digital active PFC controller, a duty cycle using the measured value of the at least one operating parameter;
• and
• outputting, by the digital active PFC controller, a pulse width modulation (PWM) signal to cause current in at least one of the coupled first and second inductors and the coupled third and fourth inductors to be interleaved.

A system comprising:

• an electric motor;
• and
• a motor drive system coupled to said electric motor, said motor drive system comprising:
• a first inductor coupled to a second inductor, said coupled first and second inductors coupled to a first input configured to be coupled to a first line of an alternating current (AC) power supply;
• a third inductor coupled to a fourth inductor, said coupled third and fourth inductors coupled to a second input configured to be coupled to a second line of the AC power supply;
• and
• a digital active power factor correction (PFC) controller configured to cause current in at least one of said coupled first and second inductors and said coupled third and fourth inductors to be interleaved.
