摘要： Methods, systems, and devices are described for an adjustment module that interacts with a parameter detection module to provide a threshold value for initiating switching of a switching module in a cyclical electronic system. Aspects of the present disclosure provide a switching module used in conjunction with an inductor that is coupled with the switching module. The threshold voltage for switching the switching module may be adjusted to provide switching at substantially zero volts while maintaining sufficient energy in the inductor to drive the voltage at a switching element in the switching module to zero volts. Such auto-adjustment circuits may allow for enhanced efficiency in cyclical electronic systems. The output of an up/down counter may be used to set another parameter that effects the performance of the cyclical electronic system in order to enhance the performance of the cyclical electronic system.

摘要： Methods, systems, and devices are described for using isolated and non-isolated circuit structures and control methods for achieving multiple independently regulated input and output parameters using a single, simple, primary magnetic circuit element. For example, structures and methods are revealed for achieving single-stage power factor correction with high power factor and multiple independently regulated outputs using a single, simple, primary magnetic circuit element. Other structures and methods are revealed for achieving multiple independently regulated outputs without power factor correction using a single primary magnetic circuit element for both isolated and non-isolated power conversion applications.

摘要： A bridgeless power factor correction system may include an AC input having a first input terminal and a second input terminal, an inductor module coupled with the first input terminal, and a switching module coupled between the second input terminal and the inductor module. The switching module may comprise a bi-directional voltage blocking switch that is configured to selectively couple the inductor module with the AC input based on an output voltage and a phase difference between an input voltage waveform and an input current waveform. The switching module may also comprise an auxiliary network for reversing a winding current to achieve zero voltage switching. An output module may be coupled with the inductor module, and provide an output to a load. The inductor module may include a magnetically coupled inductor having a primary and secondary winding. The output module may include a full or half bridge rectifier.

摘要： Methods, systems, and devices are described for a non-isolated dc-dc power converter that uses a single magnetic element and provides both a positive and a negative voltage output. The magnetic element, such as an inductor, is coupled with two or more switching modules that electrically switch the inductor to and from a voltage source, an inductor terminal, and/or a load. By electrically connecting and electrically isolating different components at various times, separate positive and negative voltage outputs are provided using the single inductor element. Switching may be controlled by a controller module, and a magnitude of the dc output voltage may be selected based on two or more resistors coupled with the controller module.

摘要： Methods, systems, and devices are described for using coupled inductor boost circuits to operate in a zero current switching (ZCS) and/or a zero voltage switching (ZVS) boundary mode. Some embodiments include a coupled inductor boost circuit that can substantially eliminate rectifier reverse recovery effects without using a high side primary switch and a high side primary switch driver. Other embodiments include a coupled inductor boost circuit that can achieve substantially zero voltage switching. ZCS and ZVS modes may be effectuated using control techniques. For example, a magnetizing current may be sensed or otherwise represented, and a signal may be generated accordingly for controlling switching of the controller.
