Abstract: In some examples, a switch-mode power supply circuit comprises a pulse generation circuit comprising an oscillator, the oscillator configured to generate first pulses using a fixed frequency regulation for a first load condition that exceeds a predefined threshold and configured to generate second pulses using a variable frequency regulation for a second load condition that does not exceed the predefined threshold. The circuit also includes a power converter coupled to the pulse generation circuit and configured to convert a first voltage to a regulated voltage using either one of the first or second pulses generated by the pulse generation circuit. The circuit further comprises an output filter coupled to the power converter and configured to produce a second voltage from the regulated voltage.

Abstract: An electronic controller is configured to provide control signals to the control terminals of the semiconductor switches of the primary converter and the secondary converter based on a commanded current or target output current; the electronic controller is configured to adjust the phase angle(s), between a respective pairs of semiconductor switches of the primary converter and second converter based on a deadtime compensation module responsive to a current error or current difference between the target output current and the observed output current. A low-pass filter facilitates estimation of the current error for compensation in the commanded current.

Abstract: 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 includes two DC/DC converters connected in parallel to one another and two DC/AC converters connected in parallel to one another. The two DC/DC converters are connected in series with the two DC/AC converters by means of two buses consisting of three DC power lines where one of the DC power lines is common to the two buses.

Abstract: A converter comprises a first circuit part and a second circuit part configured to be electrically connected with each other. Each circuit part comprises two or more switches configured to be switched for the power conversion, the switches being semiconductor switches. The two or more switches of the first circuit part are configured for a first switching operation of the first circuit part. The two or more switches of the second circuit part are configured for a second switching operation of the second circuit part. The first switching operation causes a greater electrical power loss compared to the second switching operation. The two circuit parts are configured such that the first circuit part is configured to operate at a higher operating temperature compared to the second circuit part.
