This paper proposes a new simple maximum power point tracking (MPPT) control scheme for a PV system without using conventional “mountain climbing” optimum operating point searching technique. Although no information is needed on PV array, the generated output power is maximized by utilizing limit cycle phenomena occurring on equilibrium/non-equilibrium boundary of system power flow. A parameter design procedure to determine operating period based on a theoretical model is presented. It has turned out that the operating period of limit cycle is kept constant depending on the circuit and control parameters irrespective of the insolation conditions of PV array, Availability of the proposed new MPPT control scheme has been shown by simulation and experimental results.
