Single transmitter and multi receiver (STMR) based WPT system is used to power multiple loads at a time. It consists of some limitations like long distance power transfer, mutual inductance between receiver coils and misalignment of receiver coils. this paper is going to give a detailed information about different designs of STMR, which are going to overcome the limitations of STMR. Different designs proposed by different authors are wireless power repeater system with single coil in each repeater, wireless power repeater system with two coils in each repeater, spherical strongly coupled magnetic resonant, square shape coils, maglev train IPT system and cube shaped unidirectional flux transmitter type. The above-mentioned designs are analysed and concluded a best design from it, depending up on applications and discussed about the control systems used in STMR.
