For fluctuations of the DC bus voltage in dual PWM motor drive system, which is caused by the frequent changes in motor running, the generation mechanism is analyzed. A new control strategy for dual PWM system is proposed, which is based on EL model and the load power feed forward. By using DC steady state voltage compensation and the Power load forecasting, the stable DC voltage and the unity power...
In this paper, the dynamic capacitor voltage control (DVC) is proposed, designed and applied to suppress the resonance for the high power current source converter (CSC) fed permanent magnet synchronous motor (PMSM) drives. The key is to control the capacitor voltage to follow the fundamental voltage reference dynamically. The proposed DVC affords some attractive features: Firstly, it can suppress...
In this paper, the one-comparator counter-based pulse-width-modulated (PWM) control strategy without any analog-to-digital converter (ADC), used in the DC-DC converter, is applied to the DC-AC converter with some modifications. Via some experimental results based on the field programmable gate array (FPGA), the effectiveness of the proposed control scheme is demonstrated by the DC-AC converter operating...
Stepping motors are electromagnetic incremental-motion actuators, which, when energized by a voltage and current input, index in given angular increments. Their inherent positional accuracy makes them suitable for a wide range of motion control and industrial positioning applications, especially when slow and precise movement is required. However, their speed is limited by their torque which diminishes...
Many techniques are available for control of three-phase machines to extract the best performance. However, no generalized technique exists for the application to single-phase induction motor (SPIM) drives. An application of SPIM is not just limited to fans, but it is being used in many domestic gadgets and consumer electronics applications. In this paper, a SPIM is controlled using a dynamic capacitor...
The use of induction machines as electric generator with renewable energy sources is fostered by its simple connection to the power grid, and by its intrinsic safety. In grid isolated operation the induction generator requires a proper excitation. A suitable machine excitation can be achieved relying on a current controlled voltage source inverter (CC-VSI) with a proper capacitors bank in the DC side...
