More Information
Summary:An apparatus includes an energy input module that applies an amount of energy to a primary converter of a wireless power transfer ("WPT") system. The WPT system includes secondary converter with a secondary receiver pad. The WPT system transfers energy from a primary transmitter pad to the secondary receiver pad and the secondary converter provides power to a load. The apparatus includes a coupling measurement module that measures a coupling coefficient between the primary transmitter pad and the secondary receiver pad when the primary transmitter pad and the secondary receiver pad are separated by a vertical distance and horizontally aligned at a horizontal position. The apparatus includes a coupling threshold module that determines if the coupling coefficient is above a coupling threshold, and an alignment alert module that sends an alignment alert in response to the coupling coefficient being above the coupling threshold.
