摘要： A method to compute an amount of energy taken from a battery coupled to a switching power converter is disclosed. The switching power converter charges a capacitor to a voltage and by the application of one or more control pulses to the switching power converter the voltage on the capacitor is maintained within a predetermined range having an upper voltage. The voltage on the capacitor is sampled and one or more control pulses are applied to the switching power converter to raise the voltage on the capacitor to the upper voltage. The amount of energy taken from the battery is computed based on measurement of a change in voltage on the capacitor over an elapsed time.

摘要： A switching power converter controller controls a plurality of switching power converters which provide power to a host microprocessor. A watchdog timer in the switching power converter controller counts down a timer unless it receives reset signals from the host microprocessor and the watchdog timer issues an interrupt to the microprocessor if the watchdog timer expires. The microprocessor in the switching power converter controller provides a reset command to the host microprocessor in response to receipt of the interrupt. If the host microprocessor does not respond to the reset command, the microprocessor causes the switching power supply controller to power down the power converters.

摘要： Solar panels of certain technologies may experience a degradation of their efficiency as a result of exposure to sunlight, either prior to installation or during normal operation. A direct current to pulse amplitude modulated (“PAM”) current converter, denominated a “PAMCC”, is connected to the solar panel and to a source of alternating current. The PAMCC receives direct current from the solar panel and provides pulse amplitude modulated current at its output terminals at such times that the solar panel is capable to provide current, denominated “normal operation”. The PAMCC may be reconfigured to form a buck converter and a rectifier wherein the rectifier converts power received at the output (during normal operation) terminals to provide rectified, direct current to the buck converter. The buck converter provides direct current in the forward biased direction to the solar panel, thereby reconditioning the solar panel. Alternating current received at the output terminals of the PAMCC may be provided by an electric grid or by other means, such as other solar power converters.

摘要： A circuit controls the pulse width of an output signal from a voltage controlled oscillator. The voltage controlled oscillator includes a ring oscillator comprising a plurality of series-connected inverters. In one embodiment a selector selects at least one output signal from an inverter in the plurality of series-connected inverters. An output circuit receives the selected output signal and a reference signal to provide a final output signal having a time duration proportional to the number of inverters between the inverters providing the reference signal and the output signal to the selection circuit.

摘要： Disclosed is a method of controlling an operation of a switching power converter which includes a first and second series connected transistors. Each of the transistors includes a conduction control terminal for receiving a conduction control signal. A first series of conduction control signals is applied to the control terminal of the first transistor and a second series of conduction control signals is applied to the control terminal of the second transistor, with the second series of conduction control signals being applied out of phase with respect to the first series of conduction control signals. A ratio of an input voltage to an output voltage for the series connected transistors is measured for a first spacing between an edge of a falling transition of the conduction control signal for the first transistor and an edge of a rising transition of the conduction control signal for the second transistor. The operation of the switching power converter is changed by providing a spacing having a second amount of time and the ratio of the input voltage to the output voltage for the second spacing is measured.
