摘要： A power conversion apparatus supplies power from a DC power supply to a capacitive load by a current input push-pull DCDC converter provided with switching elements Q1 and Q2. When a capacitive load voltage is not larger than a second predetermined value, a first mode is used which turns ON one of the switching elements Q1 and Q2 alternated with turning OFF both. When the capacitive load voltage is larger than the second predetermined value but not larger than a first predetermined value, a second mode is used which turns ON both of the switching elements Q1 and Q2, then turns ON one of them, then turns OFF both, sequentially. When the capacitive load voltage is larger than the first predetermined value, a third mode is used, turning ON both of the switching elements Q1 and Q2 alternated with turning ON one of them.

摘要： A noise filter is assembled to an electric power conversion device and has a metal housing casing and two capacitors connected to an external terminal of the device through which an electric power conversion circuit is connected to an external device. The two capacitors, the housing casing and the external terminal make a current loop. A magnetic flux of an alternating magnetic field generated in a part of the electric power conversion circuit penetrates in a first area and a second area formed in the current loop. A first induced noise current is induced in the current loop when the magnetic flux of the generated magnetic field penetrates in the first area. A second induced noise current is induced in the current loop when the magnetic flux penetrates in the second area so that the first induced noise current flows in a reverse direction to the second induced noise current.

摘要： A power supply system includes a plurality of DC-DC converters and at least one operating unit. The DC-DC converters are connected in parallel to one another. The at least one operating unit operates the DC-DC converters such that power is supplied through the DC-DC converters to a predetermined power-supplied object. The at least one operating unit includes a voltage controller, a current limiter, and an increasing unit. The voltage controller operates the DC-DC converters such that output voltages thereof are controlled to be respective target voltage. The current limiter limits output currents of the DC-DC converters so that they are limited with respect to a respective specified value. The increasing unit increases a specified value for at least one DC-DC converter of the DC-DC converters, when all of the plurality of DC-DC converters are activated and output current of at least one other DC-DC converter of the DC-DC converters reaches a specified value for the at least one other DC-DC converter.
