    摘要: A system and method for limiting the temperature of a burner for a cooking appliance without the use of a temperature sensor. The method includes the step of sensing the conduction state of a thermal switch and feeding back the sensed signal to control the duty-cycle (and thus “on” time) of bang-bang thermal limiting control. The power to the burner is reduced until the sensed duty-cycle (near 100%) cycling is reduced (lower frequency and amplitude) resulting in smoother power and temperature control. Preferably, the control system and method is implemented for controlling power applied to a burner for a glass-ceramic cooktop.

    摘要: A photovoltaic (PV) energy system includes a pulsed bus defined by a non-zero average value voltage that is proportional to a rectified utility grid AC supply voltage. The PV energy system also includes a plurality of PV modules, each PV module including a bucking circuit configured to convert a corresponding PV voltage into a pulsing current, wherein the pulsating bus is configured to sum the pulsing currents produced via the plurality of PV modules such that a resultant pulsing current is injected into the pulsating bus in phase with the non-zero average value voltage. A current unfolding circuit is configured to control the amount of AC current injected into the utility grid in response to the resultant pulsing current.

The photovoltaic source has power-generating characteristics defined by a family of voltage-current curves comprising points of maximum electrical power over a respective range of at least one of the following for the photovoltaic source: distinct illumination intensities and distinct temperatures. The apparatus is made up of a switching converter coupled to the photovoltaic source. The converter has an input voltage-current curve having a predefined functional relationship between the input voltage and the input current. The predefined functional relationship of the input voltage-current curve of the converter is configured to provide during operation of the converter an approximation with respect to at least some of the points of maximum electrical power for the photovoltaic source without having to perform current and voltage calculations corresponding to a maximum power from the photovoltaic source.
