In today's energy grid there are very few options to handle the severe energy swings of renewable energy sources. A Synchronverter is designed to allow an asynchronous energy source like wind mills and solar panels to appear as a synchronous energy sources. To this day, the designs have been analog with large size and large assortment of components. This paper proposes a digital design that matches...
Current control and direct power control (DPC) are popular control strategies for PWM rectifiers. In this paper, two novel control strategies are proposed to operate a rectifier to mimic a synchronous motor. One is to directly control the power extracted from the source and the other is to control the output voltage. The reactive power can be easily controlled to obtain the unity power factor. Simulation...
The fault-tolerant control of bearingless motors is vital for their safe and robust operation. In this paper, the operation of current-controlled multiphase slice permanent-magnet bearingless motors (PMBMs) with different open-circuited faulty phases is analyzed, and their fault-tolerant controllability in the general case is investigated. As an example, the feasibility of fault-tolerant control with...
In this paper, a control algorithm is proposed for AC drives without a speed sensor, building upon the idea of AC Ward Leonard drive systems developed recently. Details of how to choose the control parameters are given and experimental results are provided.
