Electrical motor with high performance and maintenance free is very atteractive for the special application in the case of limited energy sources and long operating board. Permenant magnet brush DC motor is very good candidate for such specific applications. In this paper,at first a mathematical model of the motor is persented then, a method for […]
In this paper, a new zero voltage switching isolated buck-boost DC-DC converter with active clamp circuit is proposed. The active clamp circuit in this converter not only absorbs voltage spikes across the main switch but also provides soft switching conditions for all switches. All switches are PWM controlled which simplifies the control implementation. One of […]
This paper presents a Direct Torque Control (DTC) strategy for the Permanent Magnets Synchronous Machine (PMSM). The principle relies on a Space Vector Modulation (SVM) technique that uses hysteresis comparators for the determination of the voltage module and angle, the proposed control method is simple to implement. It allows reducing the fluctuations level of the […]
