شبیه سازی مقاله Control of a Bidirectional Z-Source Inverter for Hybrid Electric Vehicles in Motoring, Regenerative Braking and Grid Interface Operations
چکیده انگلیسی:
This paper presents a battery supplying a bidirectional Z-Source Inverter (ZSI) feeding a three phase induction motor. The indirect field-oriented control (IFOC) method is used to control the induction motor speed during motoring and regenerative braking operations. The IFOC is implemented based on PWM voltage modulation with voltage decoupling compensation. In addition, this paper presents the gird interface mode with its control to charge or discharge the battery from the grid. MATLAB simulation results verified the validity of the proposed control strategies during motoring, regenerative braking and grid interface operations. A Z-source inverter is a type of power inverter, a circuit that converts direct current to alternating current. It functions as a buck-boost inverter without making use of DC-DC converter bridge due to its unique circuit topology.
نتیجه گیری:
This paper presents two control strategies of a bidirectional Z-source inverter. The first control strategy utilizes the indirect field-oriented control (IFOC) method to control the induction motor speed during motoring and regenerative braking operation modes. The second control strategy utilizes the proportional plus resonance (PR) controller to control the AC current for connecting the bidirectional ZSI to the grid. In both control strategies the Z-network capacitor voltage is controlled by a dual loop control. The first control strategy is tested during standard (acceleration, steady state, regenerative braking and standstill) and transient (overload, deceleration and light load) modes. The second control strategy is tested during battery charging from and discharging to the three phase grid. MATLAB simulation results verified the validity of the both control strategies during motoring, regenerative braking and grid interface operations.
