摘要： It is a problem of the present invention to provide an inverter device whose current detection precision is improved by checking variations in the distribution of current flowing in a shunt resistor without using a separate member. In a printed board (40) of an inverter device (20), a first conductive pattern component (51) connected to a shunt resistor (31) includes a first central region (510), a first right-side protruding region (511) that juts out on the right side from the first central region (510), and a first left-side protruding region (512) that juts out on the left side from the first central region (510). The ratio SA2/SA1 of the area SA2 of the first left-side protruding region (512) to the area SA1 of the first right-side protruding region (511) is set in the range of 0.6 to 1.6, whereby variations in the distribution of current flowing in the shunt resistor (31) can be checked.

摘要： A power converter has a transformer having three primary windings configured to receive respective phases of a three-phase alternating current (AC) input signal in a delta configuration and three secondary windings, each split into two portions, wherein the portions are coupled together in a regular hexagon. The power converter includes a rectifier having a first rectifier path coupled between taps of the secondary windings and a positive output of the power converter and a second rectifier path coupled between taps of the secondary windings and a negative output. One of the secondary windings may be reversed with respect to the other secondary windings. The primary windings may be split with a corresponding secondary winding sandwiched between portions of the primary. One of the paths may have a different inductance than the other path.

摘要： A high-frequency ac-dc power converter takes an input ac signal and converts it to an output dc signal. The converter has at least two front-end rectifier diodes arranged as a full wave rectifier of the input ac signal. A first inductor positioned at the output of the full wave rectifier. An output capacitor is connected across a load for the converter. There are at least one additional inductor and one additional capacitor. A switching circuit selectively forms different (LC) resonant circuits with the inductors and capacitors during a cycle of the input ac signal to form a dc-dc power converter.
