The ability of an electrical drive to continue operation without tripping in spite of short duration voltage sags or power supply interruptions is known as Power Failure Ridethrough capability. Critical production processes in industries require the drives to smoothly ride-through during momentary power interruptions. The reliability of the drive is dependent on the maximum duration for which a total power supply failure can be tolerated without process interruption. This paper presents a method to extend the duration of the ride-through in voltage source inverter fed vector controlled induction motor drives with a front end diode bridge rectifier. The proposed method minimises the losses in the system during the ridethrough, thereby enabling a longer ride-through duration. The method only requires a modification of the control software and hence is easy to implement. The paper also briefly describes two conventional methods used for ride-through, and compares the proposed method with the conventional methods to clearly bring out its advantage. Simulation study using MATLAB/PLECS verifies the effectiveness of the proposed method. Hardware implementation of the method on a 30 kW induction machine indicates an extension of up to 34% in the ride-through duration with the proposed method, as compared to the conventional method. © 2015 IEEE.
