摘要： Interfering effects of output ripple on measurement of output voltage and output current in a switched power converter may be obviated by taking sampled measurements at time points which are synchronized to the cause of the output ripple to drop out. Different waveform features within the switch driving signal may be used as synchronization markers for respectively determining when to take measurement samples of converter output voltage and converter current.

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.

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.

摘要： Methods and devices are disclosed for performing analog to digital signal conversion in shorter time and/or with less power consumption than that of a comparable analog to digital conversion that uses a conventional sequential approximation method based on a binary search. In one embodiment, a predictive guess is supplied as a digital first signal. The digital first signal is converted (D/A) to a counterpart, analog guess signal. A comparison is made between the analog guess signal and a received, analog input sample signal. The result of the comparison is used to improve on the initially supplied guess in a next cycle. Fewer cycles and less power is consumed if the initial guess is within a certain range of the actual magnitude of the analog input sample signal. In one embodiment, a digital modeler is used to model a process underlying the analog input sample signal and to thereby provide fairly good guesses.

摘要： A switching power supply controller coupled to a first switching power supply circuit and a second switching power supply circuit, the controller sensing voltages provided to the first switching power supply circuit and the second switching power supply circuit. Based on voltages sensed, the switching power supply controller provides signals to operate the second switching power supply in either a first or a second mode of operation. In one of the modes of operation, the second switching power supply includes a transistor which is coupled between a first source of electrical potential and an input terminal of the first switching power supply. If switching power supply controller determines that the magnitude of the first source of electric potential is sufficient to operate the first switching power supply, the switching power supply controller provides a control signal to turn on the transistor continuously.
