Problems solved by technology

But at the same time, because there is no DC bus capacitor, the high-frequency link matrix converter can only obtain energy from the grid, which reduces the dynamic response speed of the system, and can be interfered by both the grid side and the battery side, resulting in poor immunity

Abstract

The invention provides a high-anti-interference fast-response control system and method for a high-frequency link matrix converter, and belongs to the technical field of advanced control of high-efficiency power conversion systems. An output current outer loop backstepping controller obtains a reference value of an input current on an active component d axis according to a received given output current reference value and an output current and an output voltage of the high-frequency link matrix converter; an input current inner loop backstepping controller obtains a modulation ratio of three-phase current active components according to the power grid voltage active component, the power grid current active component and the reactive component; and a bipolar current space vector modulation module obtains a control pulse signal of the high-frequency link matrix converter according to the modulation ratio of the three-phase current active components and the sector, and is used for drivinga bidirectional switch of the high-frequency link matrix converter. According to the invention, overshoot and overshoot time can be reduced, and internal and external disturbance of a high-frequency link matrix converter system can be effectively resisted, so that the converter system has good dynamic performance and anti-interference performance.

Description

technical field [0001] The present disclosure relates to the technical field of advanced control of high-efficiency power conversion systems, and in particular to a high-frequency link matrix converter high-anti-interference fast-response control system and method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] In order to solve the energy crisis and alleviate environmental pollution, new energy vehicles have been developed rapidly, and countries around the world are gradually making great efforts to develop electric vehicles as a national strategy.
