Abstract: A power conversion apparatus includes a switch circuit which activates switching elements on the basis of a control signal, a feedback means which performs feedback control, a signal output means which outputs the control signal on the basis of a control variable of the feedback control, and a mode switching means which controls switching operation of the switch circuit by switching an operation mode between a normal mode and an intermittent mode in which the number of operations is less than that in the normal mode. The mode switching means changes timing of switching from the normal mode to the intermittent mode, on the basis of either or both of a first detection value which is an input value inputted to the switch circuit and a second detection value which is an output value outputted from the switch circuit.

Abstract: In a power converter, a deviation calculator calculates, in each cycle, a deviation between a value of an input electrical parameter of a switch circuit and a target value selected by a selector in a previous cycle. The input electrical parameter depends on the input power to the switch circuit. A second calculator calculates, in each cycle, a value of a second feedback controlled variable such that the value of the second feedback variable approaches the value of the input electrical parameter. A controller controls, in each cycle, the selector to select one of the value of the first feedback controlled variable and the value of the second feedback controlled variable as the target value for the next cycle according to the deviation calculated by the deviation calculator.

Abstract: In a power converter, a feedback controller feedback controls a manipulated variable based on a first electrical parameter depending on input power and a feedback controlled variable determined for output power. A dead-time determiner determines a value of the dead time as a function of a boundary condition variable depending on at least one of the input power and the output power. The boundary condition represents a reference for determining whether the power converter is operating in a continuous conduction mode or a discontinuous conduction mode. The continuous conduction mode is designed for a current to be continuously flowing through an inductor included in the power converter or a load as an inductor current. The discontinuous conduction mode is designed for the inductor current to be discontinuously flowing through the inductor.

Abstract: In a power converter, a driver drives a switching element using a manipulated variable therefor to convert input power into output power. A first measuring unit measures a value of a first electric parameter depending on the input power. A first determiner determines, from the measured value of the first electric parameter, a first feedback controlled variable. A second measuring unit measures a value of a second electric parameter indicative of the output power, and a calculator calculates, based on the measured value of the second electric parameter and a command value for the second electric parameter, a second feedback controlled variable. A selector selects, based on the measured value of the first electric parameter, one of the first feedback controlled variable and the second feedback controlled variable. A second determiner determines the manipulated variable using the selected one of the first and second feedback controlled variables.
