Design-oriented stability criteria of a v2 control compensated with inductor current of a boost converter for shipboard power systems

This paper deals with remote control of power converters for marine applications where a boost converter is controlled with a v² control compensated with inductor current. This control has a fast inner loop where the control is able to react independently from the reference signal and a slow outer loop that changes the reference signal to regulate tightly the output voltage. This way, the control is decoupled in two parts where the fast inner loop is on-board of the ship and the slow outer loop is remotely controlled on-shore. As robustness of the system is required, the stability of the inner control has to be analyzed. This paper proposes a design-oriented stability criterion for the boost converter controlled with v² control compensated with inductor current so that designers can select the parameters of the control and know how to design the power stage in order to increase the stability region of the control.
