Latest Patents

One of Michael's latest patents is a motor drive system that includes a first inverter connected to one end of an open-end winding of a three-phase motor. This system rectifies input voltage from a single-phase AC power source into a rectified voltage for the first inverter. Additionally, a second inverter is connected to another end of the open-end winding and includes a DC link capacitor. The control unit manages the first inverter to ensure that the output voltage is in phase with the motor current. It also controls the second inverter to supply reactive power to the three-phase motor, making the output voltage orthogonal to the motor current. This innovative design aims to optimize the instantaneous power supplied from the DC link capacitor to the motor.

Another notable patent is an AC-AC converter circuit that converts an AC voltage into a further AC voltage. This circuit features a rectifier that rectifies the AC voltage and an inverter that generates the further AC voltage. An AZ source circuit is integrated between the rectifier and inverter circuits, enhancing the efficiency of the conversion process.
