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 Qand Q. 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 Qand Qalternated 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 Qand Q, 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 Qand Qalternated with turning ON one of them.
