Abstract: A non-isolated DC-DC resonant conversion control circuit and a control method therefor. The control circuit, by connecting in series an inductor (L) and a capacitor (C) that are resonant, allows a current flowing through the inductor (L) to be provided with a sine wave. The form factor of the sine wave is small, the conduction loss is low, and loss of the circuit is significantly reduced. The control method not only allows the adjustment of a phase shift angle to allow a transistor to implement zero voltage switching (ZVS) conductance, but also allows the adjustment of a switching frequency; therefore, the adjustable range of a voltage (Vo) and that of the power of an output interface are increased, thus implementing non-isolated wide-range DC-DC resonant conversion.
