- Abstract
- Active power decoupling circuits have emerged to eliminate the inherent ripple power at twice the grid frequency in single-phase power electronics systems. However, this requires additional passive components and power switches, which increases the cost and volume of the system. This paper proposes a circuit configuration in an electric vehicle system to build power decoupling circuits that employ a reduced number of extra components. In this proposed circuit configuration, three inductors and six switching devices from the motor and the inverter circuit are used to build active power decoupling circuits during battery charging time. In addition, this paper proposes a robust voltage control method with a virtual d-q current controller and the interleaved pulse width modulation technique. The proposed system and its control method can improve control performance and achieve low-cost battery chargers with a high power density. MATLAB-Simulink simulations and experimental verifications based on hardware-in-the-loop-simulations and rapid-control-prototyping systems are performed to verify the effectiveness of the proposed system and control algorithm.
