Abstract:
The alternating-current power supply device  1  has: an alternating-current generation bridge  10  for obtaining an alternating-current output; PWM control bridges  20, 30,  each including two switch components; and a coupling reactor  40  connected to the PWM control bridges  20, 30.  The coupling reactor  40  includes: a core  43;  and windings  41, 42  which are connected at one end to respective output ends of the PWM control bridges  20, 30  while being coupled with each other via the core  43.  The windings  41, 42  are respectively wound in such directions that magnetic fluxes generated in the core  43  cancel each other out.

Claim (Index 10):
An alternating-current power supply device comprising:\n an AC generation bridge for producing an AC output; first and second PWM control bridges each including two switching devices; and a coupling reactor connected to the first and second PWM control bridges, wherein the coupling reactor includes:\n a core; and \n first and second windings one end of each of which is connected to respective output terminals of the first and second PWM control bridges, the first and second windings being coupled together via the core, \n the core is composed of at least a first core and a second core in combination, the first and second cores are both made of a same material having anisotropic insulation resistance, and are formed such that an insulation resistance thereof does not vary along a direction of a magnetic flux passing through the first and second cores, the first and second windings are wound around the first core in such directions that magnetic fluxes which the first and second windings generate inside the first core cancel each other, and neither of the first winding nor the second winding is wound around the second core, and the second core is arranged such that the magnetic fluxes passing through the second core generate a leakage inductance in the coupling reactor.
