- Abstract
- This paper describes a new sensorless control using self-dynamics without an external signal injection. Instead of the signal injection, it utilizes the self-dynamics of the control loop that inherently adjusts the magnitude of inverters current and voltage in the switching frequency range. Due to no existence of the external signal, the proposed method provides several advantages including reduction of audible noise and core loss, while achieving a good dynamic performance with a high current controller bandwidth. The detail operation principle and the control structure are described, various simulation and experiment results are provided in order to verify the effectiveness and feasibilities.
