In order to design a high performance power electronics circuit, a precise simulation environment is essential for the controller design. In this paper, a power electronic circuit real-time simulator was designed and realized on a DSP chip. The dynamic equations of a power electronics circuit were coded on a Texas Instruments (TI) made C6416 fixed point DSP. Meanwhile, the interrupt interface of the...
This paper is concerned on FPGA design for control implementations of four switch three phase inverters (B4, FSTPI). This paper is to present a space vector PWM algorithm for four switch three phase inverters (B4, FSTPI) based on the one for six switch three phase inverters (B6, SSTPI) (principle of similarity) where the ???? plan is divided into 6 sectors and the formation of the required reference...
Active front-end converters with bidirectional power flow capability have been extensively used for utility applications of power electronics. Large passive filters are normally required at the grid side of the converter to mitigate switching EMI noise. This may become a critical issue, in terms of installation space and potential resonance of the passive filter. This paper proposes a hybrid active...
Real-time simulation is an important issue in the design of power electronic systems, especially in the context of hardware-in-loop (HIL) simulation. This paper is concerned with the development of a real-time simulation environment that is low-cost and can be easily set up in an educational laboratory. Any real-time simulation environment needs three essential components: a mechanism to accept a...
A new very high efficiency 10 kW isolated R4 boost converter for low-voltage high-power fuel cell applications is presented. Using a new concept for partially paralleling of isolated boost converters, only the critical high ac-current parts are paralleled. Four 2.5 kW power stages, consisting of full-bridge switching stages and power transformers, operate in parallel on primary side and in series...
This paper discusses the importance of a simulation study of the Taiwan Electrical Fuel Cell Power Scooter. This study applies a more detailed modeling which is complex as existing modeling methods, yet not more difficult to solve numerically. In most simulation studies, the influence of non-linearity (for example, saturation, losses, reluctance effects) of the power electronics and electrical machine...
Digital controller platforms for power electronic converters have typically been based on a single high performance digital processor, often coupled with a programmable logic gate array. The digital processor is usually a digital signal processor (DSP). Often, a highly optimized real-time operating system provides multitasking features for the controller code execution on a single processor core....
Design procedure for power electronics circuit structures has recently been discussed for high power density circuits or thin structure converters. Then the control circuit may be connected close to the power circuit. When a pulse current flows into the power circuit, it radiates a magnetic field and it may produce a near field noise voltage in the control circuit and this can be a cause of malfunction...
This paper investigates the potential savings using improved motor and power electronic technology and improved motor control, for different heating ventilation and air-conditioning load profiles. Different energy labels (eff1-eff3) and different voltage/frequency (V/Hz) control have been investigated. The general conclusion is that economical savings will be made, both for an induction motor (IM)...
This paper presents a smart control approach for digitally controlled forward type multiple-output dc-dc converter. In this case, the central problem of design is how to decide the integral coefficient. Since the decision of integral coefficient depends on the static characteristics, the selected integral coefficient is not suitable to perform the superior dynamic characteristics. Then, it is important...
Wind energy conversion systems have become important in the research of renewable energy sources. This is not a small part due to the rapid advances in the size of wind generators as well as the development of power electronics and their applicability in wind energy extraction. However, wind energy has a drawback of having only 1/800 density as compared to that of water energy, and it does not remain...
With the application of multilevel inverter in the high voltage and large power occasions in recent years, its modulation strategy has become a research hot point in the field of power electronics. As STATCOM is a typical application of multilevel converter, its common modulation strategies such as Step Wave modulation, Specific Harmonic Elimination modulation, Carrier PWM modulation, Space Vector...
