Abstract
The present disclosure provides a control method of a power conversion device including first and second bridge arms and two transformers. The first bridge arm includes the first, second and third switches serially connected. The second bridge arm includes the fourth, fifth and sixth switches serially connected. The control method includes: controlling the first and fourth switches to operate with duty cycle and being 180 degrees out of phase; controlling control signals of the third and fourth switches to be complementary, and controlling control signals of the sixth and first switches to be complementary; when the duty cycle being less than or equal to 0.5, controlling the second and fourth switches to switch synchronously, controlling the fifth and first switches to switch synchronously; and when the duty cycle being greater than 0.5, controlling the second and sixth switches to switch synchronously, controlling the fifth and third switches to switch synchronously.
