An energy input module 202 applies an amount of energy to a primary converter 106 of a wireless power transfer ("WPT") system 100, which includes secondary converter 108 with a secondary receiver pad 120. The WPT system 100 transfers energy from a primary 5 transmitter pad 114 to the secondary receiver pad 120, and the secondary converter 108 provides power to a load. A coupling measurement module 204 measures a coupling coefficient between the primary transmitter pad 114 and the secondary receiver pad 120 when the primary transmitter pad 114 and the secondary receiver pad 120 are separated by a vertical distance and horizontally aligned 10 at a horizontal position. A coupling threshold module 206 determines if the coupling coefficient is above a coupling threshold, and an alignment alert module 208 sends an alignment alert in response to the coupling coefficient being above the coupling threshold. 本发明提供了种能量输入模块(202)，所述能量输入模块将定量的能量施加至无线功率传输("WPT")系统(100)的初级转换器(106)，所述无线功率传输("WPT")系统包括具有次级接收器垫(120)的次级转换器(108)。
