Verifying digital control programs for a complicated power electronic system is usually time consuming. In this paper, a circuit simulation method to verify digital control programs is investigated. This method uses the C block provided by PSIM to integrate digital control program code into the circuit simulation environment. A program module packaging technique is first exploited to guarantee the...
DC-link current sensing enables adjustable speed drives to be designed compactly. Except for the low-impedance earth-fault protection the whole drive is protected by a single current-sensing element as well as drives with three current sensors on the output phases. A new indirect detection method for improving the low-impedance earth-fault protection of adjustable speed drives with a low-side DC-link...

Based on brief introduction of the characteristics of power electronic technology and Multisim. The application of Multisim is given with PWM for example. Practice shows that the introduction of Multisim raise the student's enthusiasm. The class effect is good.
This article compared and analyzed the three-phase bridge voltage-type PWM rectifier circuit simulation software at first, and then focused compared the data of different device simulation of the circuit with Psim for the given parameters. Simulation results show that the inductor, capacitor parameters and the unbalance of grid has the impact on circuit performance, and the function is crucial.
The growth of fuzzy logic applications led to the need of finding efficient ways to implement them. The FPGAs (Field Programmable Gate Arrays) are reconfigurable logic devices that provide mainly practicality and portability, with low consumption of energy, high speedy of operation and large capacity of data storage. These characteristics, combined with the ability of synthesizing circuits, make FPGAs...
Translation of power electronic circuit designs from simulations into actual hardware can give rise to difficulties, regarding the implementation of control functions with embedded controllers. This task is even more difficult when the power converter must operate connected to the grid. A design framework is described in this paper, which is suitable for testing and debugging software implementations...
The electric power generation using hydro potential is increasing around the globe due to many reasons like increasing power demand, deregulated markets, and environmental concerns etc. At the same time, extended transmission networks, higher degrees of interconnection between different networks, and fast connection and disconnection of the heavy loads demand flexible, fast power generation and consumption...
