Latest Patents

Anupama holds a patent for a "System for operating a three-phase variable frequency drive from an unbalanced three-phase or single-phase AC source." This invention involves a variable frequency motor drive that includes a converter with a rectifier. The rectifier connects to an AC power source and converts the AC power to DC power. A DC bus is linked to the rectifier circuit, with at least one bus capacitor across the DC bus. The inverter receives DC power from the DC bus and converts it to AC power to drive a motor. A controller is operatively connected to the converter, featuring a speed control that manages the inverter based on a speed command to maintain the desired motor speed. Additionally, a speed foldback control measures DC bus ripple voltage and adjusts the speed command accordingly.
