The generalized solution of the minimum time current control in the systems are presented in this paper. With the generalized solution, the minimum time current controller can be easily applied to all the 3-phase balanced system. Through the simulation and the experiment, it is observed that the proposed controller has much less transient time than the conventional synchronous PI regulator. Abstract - The structure of current control loop of an induction machine drive determines decisively the dynamic performance of the overall system. Fast current control is a prerequisite for dynamic decoupling between the torque and the flux linkage state variables.
Standard solutions are well established for drives in the low and medium power range.
The controller determines a set of space vectors from a region detector and applies a space voltage vector selected according to the main hysteresis current controller. A set of space vectors including the zero voltage vector to reduce the number of switchings is determined from the information of the wider current errors than those of the main hysteresis current controller. Abstract - Shunt active power filters are connected in parallel with the electricity supply network. If the AC mains has a neutral conductor it is desirable to compensate the mains harmonic currents zero sequence components. This can be achieved with a four wire PWM voltage converter connected to the AC mains.
