Abstract
A power conversion apparatus includes: a first power terminal; a switching circuit including first switching devices configured to be turned on/off based on a first driving signal; a transformer; a rectifying circuit including second switching devices configured to be turned on/off based on a second driving signal; a smoothing circuit; a second power terminal; and a control circuit. In a first period before electric power is supplied from the first power terminal toward the second power terminal, the control circuit generates a first threshold increasing with the passage of time, and performs, when a voltage value of a voltage at the first power terminal reaches the first threshold, switching from an output state in which the second driving signal is outputted to an output stop state in which output of the second driving signal is stopped, or switching from the output stop state to the output state.
