摘要： This application provides a resonant switched capacitor converter and a power supply system. The resonant switched capacitor converter includes a control module, a first capacitor, a plurality of resonant modules, and a plurality of second capacitors connected in series. The first capacitor is connected in series to the plurality of second capacitors connected in series. One resonant module may correspond to one second capacitor. The resonant module includes a first switch unit, a resonant unit, and a second switch unit. The control module may be connected to the resonant modules, and the control module may be configured to control, based on a target output voltage gain, switches in a first switch unit and a second switch unit in each resonant module to be turned on or turned off, so that an output voltage gain of the resonant switched capacitor converter reaches the target output voltage gain.

摘要： The present invention relates to an inverter topology with a DC/DC voltage boost converter, which is also scalable. The arrangement of converters and power lines used in this topology makes it possible to maximize the efficiency of the energy conversion that takes place in photovoltaic plants or in any other system based on power transmission that use DC power lines, reducing the values of current used for a given power level. The inverter comprises two DC/DC converters (3,4) connected to one another and two DC/AC converters (5,6) connected to one another. The two DC/DC converters (3,4) are connected with the two DC/AC converters (5,6) by means of two buses (11-9, 12-10) consisting of three DC power lines (13, 14, 15) where one of the DC power lines (14) is common to the two buses (11-9, 12-10).

摘要： A digital controller configured to inject a signal into a digital feedback path that facilitates regulation of a power converter and measure the corresponding phase, gain, or frequency. The digital controller may also include an adaptive tuning controller for adjusting power converter operating attributes based in part on the measurements. In an exemplary embodiment, the adaptive tuning controller uses the phase, gain, and/or frequency measurements to adjust the digital feedback signal. In an exemplary embodiment, the adaptive tuning controller compares the operating measurements with desired values and generates adjusted operating attributes. In accordance with an exemplary embodiment, the monitoring and adjusting of the digital feedback signal occurs while the digital controller is regulating a power signal in the power converter.

摘要： Composition and evaluation are shown about the feedback circuit and its circuit constants which stabilize the direct-current output voltage obtained by rectifying a high-frequency carrier outputted from a resonance circuit against a wide range of load. An equivalent power supply is introduced, including a virtual resonance circuit and a virtual rectification circuit. The virtual resonance circuit, supplied with the same input with a resonance circuit, outputs the envelop of such the carrier that is outputted by the resonance circuit. The virtual rectification circuit, supplied with the envelop of the carrier, works as a first-order delay and outputs the direct-current voltage equivalent with the output of a rectification circuit. The equivalent power supply is described by the system of differential equations. The sufficient condition that the system of differential equations becomes stable is given. The feedback circuit satisfying the sufficient condition is shown to be stable by simulation.
