Document Type and Number:
WIPO Patent Application WO/2017/179578
Kind Code:
A1
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.
