Abstract
In a control device, a load determiner determines whether a power converter is in a high-load state or a low-load state. A high-load controller controls on-off operations of the first rectifiers such that on durations of the first rectifiers are respectively synchronized with each other when it is determined that the power converter is in the high-load state. A low-load controller controls on-off operations of the first rectifiers to reduce the on durations of the first rectifies synchronized with each other when it is determined that the power converter is in the low-load state.
