Abstract: 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 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.

Abstract: 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.

Abstract: An apparatus controls a DC-DC converter that converts an input voltage to an output voltage. The DC-DC converter includes a switching element having a duty ratio controlled by the apparatus to regulate the output voltage, a first transformer, a second transformer and a capacitor. A terminal voltage applied between input and output terminals of the switching element varies depending on the duty ratio and the input voltage.
