—A novel switched-capacitor inverter is proposed. The proposed inverter outputs larger voltage than the input voltage by switching the capacitors in series and in parallel. The maximum output voltage is determined by the number of the capacitors. The proposed inverter, which does not need any inductors, can be smaller than a conventional two-stage unit(More)
—The Class DE inverter offers high-efficiency power conversion under high operating frequency (megahertz order) with low switching noises and low switch voltage stress. It has been applied to dc/dc converters as high-density power sources. Conventional converters with the Class DE inverter are controlled by varying the operating frequency, the switch duty(More)
—This paper presents a new control scheme for a Class DE inverter, that is, frequency modulation/pulsewidth modulation (FM/PWM) control. Further, the FM/PWM controlled Class DE inverter is analyzed and we clarify performance characteristics. Since the FM/PWM controlled inverter has two control parameters , namely, the switching frequency and the switch-on(More)
Comparison and evaluation of maximum power point tracking (MPPT) algorithms for photovoltaic (PV) arrays are often carried out by computer simulation because any irradiation and temperature condition can be set up and repeated. This paper proposes a new simple calculation method for computer simulation to evaluate any MPPT algorithm. The proposed method(More)
