CURRENT CONTROLLER DEVICE AND VECTOR CONTROL METHOD FOR CONTROLLING POWER CONVERSION |
摘要 |
A current controller device using a vector control algorithm for controlling conversion of DC power into AC power is provided. The controller device has an open loop control loop gain and produces a first and a second voltage demand signals based on a first and a second current demand signals, a first and a second current feedback signals, a first and a second voltage feedback signals. The open loop control loop gain depends on frequencies of the first and second current feedback signals. A first and a second filters are provided at a first and a second current feedback inputs respectively. The first and second filters each have a filter characteristics to reduce the frequencies of the first and second current feedback signals at which the open loop control loop gain is greater than unity and has a phase less than or equal to minus 180°.
