An EPS system requires large electrical power depending on steering torque. Recently, the required steering torque is getting larger especially for luxury sedans and large Sports Utility Vehicles. In heavy vehicles, the steering without driving and the emergency steering are becoming a very heavy load for a conventional 12 V battery system. Therefore, it is important to estimate the battery power management and the voltage behavior using the multi domain simulation for concept planning. The purpose of this research is to show that multi domain simulation is effective to discuss power electronics system and power network in the vehicle. This paper describes modeling method for an EPS system using VHDL-AMS. Static steering and dynamic steering results were validated in comparison with experimental data.

This paper proposes a new generation method of position reference without the resonant frequency and phase error for industrial robots. It is important for the industrial robot to drive high speed and high accuracy. However, the vibration phenomenon is generated by the resonant frequency in such cases. Conventionally, the notch filter is used to suppress the vibration phenomenon. It is able to eliminate a particular frequency. However, it also has a disadvantage that the reference phase error is generated. Generating the phase error in the reference, the critical error is generated in the locus which the robot draws. Therefore, the accuracy of the robot is deteriorated by using the notch filter. The proposed method overcomes this problem by using the compensation gain. The compensation gain is used to calculate the reference phase error. The compensation of the reference phase error is performed by the feedforward. The simulation results and the experimental results show that the proposed method is superior to suppress the resonant frequency and improves the phase error.

In this paper, a double connected three-phase hybrid rectifier employing thyristors and self-turn-off devices without input transformers is proposed. Two three-phase bridge rectifiers with auxiliary circuit injecting harmonic currents are connected in parallel. This system can be performed as the conventional 24-step rectifier on the optimum conditions. In this paper, circuit performances of the proposed method are discussed by graphical analysis, and optimum parameters are derived. Then, effects on harmonics reduction can be clarified by simulations.

This paper proposes a new voltage-balancing circuit for the split dc voltages in a diode-clamped five-level inverter. The proposed circuit is based on a resonant switched-capacitor converter (RSCC), which consists of two half-bridge inverters, a resonant inductor and a resonant capacitor. A new phase-shift control of the RSCC is proposed to improve voltage balancing performance. As a result, it is possible to reduce the inductor to one tenth in volume as compared to a conventional voltage-balancing circuit based on a buck-boost converter. Experimental results are shown to verify the viability of the RSCC-based voltage balancing circuit.

The objective of this paper is analysis of output voltage distortion of a PWM inverter with LC filter caused by device voltage drop. The goal of this study is to find out how to compensate the output voltage distortion of PWM inverter caused by device voltage drop to realize precise output voltage. The output voltage distortion is mainly caused by dead time and device voltage drop. There are a lot of studies about distortion is mainly caused by dead time. There are, however, only few studies about device voltage drop. especially considering LC filter effect. In this paper, the authors theoretically derived the output voltage distortion of PWM inverter with LC filter caused by device voltage drop in order to estimate the distortion caused by drop in advance. The distortion was analyzed from the view point of frequency analysis and total harmonic distortion (THD). These results may allow appropriate design of PWM inverter with output voltage compensation. Theoretical analysis was verified through simulations and experiments.

New emerging micro gas turbine generator sets and turbocompressor systems push the speed limits of rotating machinery. To directly connect to these applications, ultra-high-speed electrical drive systems are needed. Therefore a 1 kW, 500000 rpm machine and the according power and control electronics are designed and built. This paper includes design considerations for the mechanical and electromagnetic machine design. Furthermore, a voltage source inverter with an additional dc-dc converter is described, and sensorless rotor position detection and digital control is used to drive the machine. Finally, the hardware and experimental results are presented.

We designed and built a trial small size and ultra-high speed motor of 2 poles, 5kW and 240,000rpm as the target. And we had described our prototype ultra-high speed drive system and some experimental results in previous papers. But the evaluation of this kind of motor drive system is difficult only by the experiments. Then we also had described the electric and magnetic coupled analysis which was used not only the motor model from FEM but also the drive and control system models in the circuit simulation. This paper explains the ultra-high speed drive system including improved control method and presents experimental results using redesigned motor, and we illustrate the confirming availability of the total drive system model created by using VHDL-AMS and C-language as well.

Phase, frequency, and amplitude of single-phase voltages are the most important and basic information required for single-phase grid connected applications. This paper proposes a new method for estimating instantly and adaptively phase, frequency, and amplitude of frequency-varying single-phase signals for such applications, which is a new PLL method based on a new structure. The proposed method has the following attractive features: 1) the estimation system results in a nonlinear system, but it can be stabilized; 2) all subsystems constructing the system can be easily designed; 3) two-phase signal generator can tune a single system-parameter adaptively to varying frequency of the injected signal; 4) high order PLL-controllers allowing fast tracking can be stably used; 5) even in hostile envelopments, favorable instant estimates can be obtained. This paper proposes the estimation method, and verifies its usefulness by extensive numerical experiments.

This paper presents an integrated framework for modelling inverter performance and evaluating power devices in hybrid electric vehicle drives. Based in MATLAB/Simulink, it uses a novel method of decoupling the device and inverter simulation to maintain high accuracy of power losses and devices temperatures, and achieve faster than real time inverter simulation. An illustration is given for a full hybrid vehicle for different driving cycles. Device models are included for silicon carbide Schottky diodes as well as silicon IGBTs and PIN diodes, allowing evaluation of the new material devices. The simulation framework offers the potential to rapidly improve the inverter and powertrain design process, and to evaluate device selection quickly.
