Abstract

The presence of ripple power in a converter system has a negative influence on both control performance and reliability. Active power decoupling (APD) is a practical technique to deal with such problems. However, the APD method requires extra sensors on the LC branch, which increases the complexity and cost of the control system. This paper puts forward a new APD method to handle undesirable ripple power for H-bridge PWM converters. When compared with previous APD methods, the proposed APD method eliminates the current and voltage sensors on the LC branch by utilizing a ripple voltage control loop. Then, both the cost and reliability of the converter system are improved. To improve the control performance, an APD method that only has a voltage sensor in the LC branch is also discussed. Simulation results show that the DC-link voltage ripples can be decreased due to the application of the proposed APD method. Finally, the effectiveness of the proposed method is verified by the experimental results.
