Abstract: Embodiments of this application provide a converter control method, a converter control apparatus, and a readable storage medium. The control method includes: obtaining a real-time input voltage and a real-time output voltage of a converter; determining a corresponding real-time closed-loop control output value of the converter based on the real-time input voltage and the real-time output voltage by using a closed-loop control algorithm; determining a real-time control strategy of a switch tube of the converter from at least three control strategies based on the real-time closed-loop control output value; and controlling the switch tube based on the determined real-time control strategy. The control method is used to implement efficient and high-precision voltage stabilization control.

Abstract: The present disclosure discloses a hybrid five-level bidirectional DC/DC converter and a voltage match modulation method thereof. The converter includes a first input filter capacitor Cinp and a second input filter capacitor Cinn, an output filter capacitor Co, a DC voltage source, a primary-side hybrid five-level unit, a primary-side two-level half bridge, a secondary-side single-phase full bridge H2, a high-frequency isolation transformer M1, a high-frequency inductor Ls, and a controller. A positive pole of a DC bus of the primary-side hybrid five-level unit is coupled to a positive pole of the corresponding DC voltage source and to a positive pole of the input filter capacitor Cinp respectively. A negative pole of the DC bus of the primary-side hybrid five-level unit is coupled to a negative pole of the corresponding DC voltage source and to a negative pole of the input filter capacitor Cinn respectively.

Abstract: An electric circuit for regulating power transfer in a power grid includes a compensator circuit arranged to be connected between outputs of one or more power sources and a point of common coupling in the power grid. The compensator circuit is arranged to detect one or more electrical properties associated with the outputs and one or more electrical properties associated with the point of common coupling; and provide, based on the detection, a voltage output to emulate a resistor for suppressing filter resonance associated with the one or more power sources and to reduce equivalent impedance of the power grid.
