摘要： A power control system includes a switching power converter and a controller, and the controller responds to a time-varying voltage source signal by generating a switch control signal having a period that varies in accordance with at least one of the following: (i) the period of the switch control signal trends inversely to estimated power delivered to a load coupled to the switching power converter, (ii) the period of the switch control signal trends inversely to instantaneous voltage levels of the voltage source signal, and (iii) the period of the switch control signal trends directly with a line voltage level of the time-varying voltage source signal. In at least one embodiment, the controller achieves an efficient correlation between the switching period with associated switching losses and the instantaneous power transferred to the switching power converter while providing power factor correction (PFC).

摘要： A delta-sigma analog-to-digital converter (ADC) having a serialized quantizer output has a data rate greater than a quantization rate of the delta-sigma modulator, but less than a bit rate determined by the product of the number of bits required to represent the input to a feedback digital-to-analog converter and the quantization rate. Additional information can be encoded in the serial bit stream by selection among redundant codes based on the value of the additional information. The serial bit stream may encode differences between successive quantizer output samples and the additional information may include the absolute value of the quantizer output, synchronization information and/or framing information for distinguishing data corresponding to multiple ADC input channels.

摘要： A cascaded switching power converter for coupling a photovoltaic (PV) energy source to power mains provides a high-efficiency and a potentially simple control mechanism for AC solar energy conversion systems. The PV energy source charges a capacitive storage element through a DC-DC converter, and an inverter couples energy from the capacitive storage element to the mains supply. The DC-DC converter is controlled so that ripple present on the capacitive storage element due to current drawn by the inverter is not reflected at the input of the DC-DC converter, which is accomplished by varying the conversion ratio of the DC-DC converter with the ripple voltage present across the capacitor. The average voltage of the capacitor can also be increased with increases in the available power output from the PV energy source, so that a corresponding increase in power is transferred to the mains supply.

摘要： A light emitting diode (LED) lighting system includes a PFC and output voltage controller and a LED lighting power system. The controller advantageously operates from an auxiliary voltage less than a link voltage generated by the LED lighting power system. The common reference voltage allows all the components of lighting system to work together. A power factor correction switch and an LED drive current switch are coupled to the common reference node and have control node-to-common node, absolute voltage that allows the controller to control the conductivity of the switches. The LED lighting system can utilize feed forward control to concurrently modify power demand by the LED lighting power system and power demand of one or more LEDs. The LED lighting system can utilize a common current sense device to provide a common feedback signal to the controller representing current in at least two of the LEDs.

摘要： A transformer-isolated analog-to-digital converter (ADC) feedback apparatus and method provides reduction of circuit complexity in high power/high voltage systems having a transformer-isolated sensing circuit. The feedback apparatus is a circuit including an ADC for receiving an analog input signal and a transformer having a first winding that receives a modulated output of the analog-to-digital converter. A second winding of the transformer provides an isolated data output of the ADC. A demodulator is coupled to the second winding of the transformer and demodulates the isolated output to generate a digital representation of the analog input signal. The ADC may be a delta-sigma converter and the demodulator may be the corresponding decimation filter. The circuit further includes an isolation circuit for introducing a clock signal and/or power supply waveform at the second winding of the transformer, so that the ADC circuit is supplied with an isolated clock and/or an isolated power supply.

摘要： A method and system monitor gate charge characteristics of one or more field effect transistors in a switching power converter to detect an end of an inductor flyback time interval. The switching power converter includes a switch coupled to an inductor to control current flow in the inductor. When the switch turns OFF, a collapsing magnetic field causes the inductor current to decrease and the inductor voltage to reverse polarity. When the magnetic field completely collapses, the inductor current goes to zero. At the end of the inductor flyback time interval, a voltage is induced across a Miller capacitance of the switch. The voltage can be detected as a transient change in the gate voltage of the switch. A switch gate sensor detects the gate voltage change associated with the end of the inductor flyback time interval and provides a signal indicating an end of the inductor flyback time interval.
