In the simulation of photovoltaic (PV) power conditioning systems, PSIM is a widely accepted circuit simulation platform because of its fast speed and C-code support. PSIM provides two kinds of generic PV panel models: functional model and physical model. Whereas the functional model simulates PV in the standard test condition (STC) only, the physical model can emulate changing PV characteristics under varying temperatures and irradiation conditions and is thus more suitable for system simulation. However, the physical model requires complicated parameters from users, and thus it is prone to errors and is difficult to use. In this study, a new PSIM model for PV is presented to solve these problems. The proposed model utilizes manufacturers' datasheet values specified under STC only and excludes user-defined information from input parameters. To achieve good accuracy even in varying environmental conditions, single-diode model parameters are successively tuned to a time-varying virtual datasheet. Comparison with a conventional physical model shows that the proposed model provides more accurate simulation according to error analysis based on the EN50530 standard.

In the paper, a three-phase-in three-phase-out Matrix Converter(MC) for the PMSM Is simulated by the PSIM simulator. A lighter L-C filters are installed at the input side of the Converter to remove the current harmonics around the switching frequency. In modelling the Matrix Converter, the PSIM is the powerful tool that the basic researches can be quickly performed within the given periods, because the simulation calculation by PSIM is very fast, compared to other simulators such as Matlab, Saber, and Pspice.

This paper presents a method to identify the equivalent circuit parameters by experiment results of supercapacitor model based on transmission line. In order to validate this method, a model of supercapacitor is verified and implemented by using the PSIM software. Experimental and simulation results are compared to verify the electric modeling of supercapacitors.

The importance of energy is growing according to the energy shortage and environmental concerns. Accordingly, in order to solve the problems about the use of fossil fuel, a renewable energy sources are needed. Global renewable energy power industry's position in the renewable energy market becomes important and new technology development is also essential. MG set composed by the induction motor and permanent magnet synchronous generator for simulating a renewable energy source is based on a suitable experiment equipment. The torque generated by applying a voltage to the induction motor in MG set is used as an input of the permanent magnet synchronous generator. In Psim simulation, the characteristics of the induction motor model was formulated and the output torque characteristics of the motor was controlled using the induction motor side inverter, In this paper, the comparison analysis between Psim simulation and the output characteristics of the MG set is performed in order to identify a renewable energy power system more accurately.

본 논문에서는 직렬형 하이브리드 자동차의 운전특성을 분석하기 위한 PSIM 시뮬레이터의 개발에 대하여 기술한다. 직렬형 하이브리드 자동차는 엔진이 전동기와 전기적으로 결합되어 있으며 전동기의 출력에 의해서만 구동된다. 엔진/발전기, 전동기, 기어와 같은 파워트레인 각 구성요소들의 정격은 에너지 개념을 이용한 시스템과 Electrical Peaking Hybrid (ELPH)를 이용하여 모델링할 수 있는데, 설계된 하이브리드 자동차를 개발된 PSIM 시뮬레이터를 이용하여 특정 운전주기 하에서 평가하고 분석하였다. 기계적 제동이 사용되는 경우와 회생제동이 사용되는 경우 각각에 대하여 전동기의 평균 입력을 비교하였으며 시뮬레이션 결과를 바탕으로 직렬형 하이브리드 자동차의 연비를 분석하였다.

Magnetic circuit is a physical modeling method that is useful in designing and analyzing power transformers, especially for a priori evaluation of leakage and magnetizing inductance before actual production. In this study, a novel modeling approach that uses PSIM magnetic elements adopting gyrator and permeance-capacitances is investigated. A formula to determine the permeance-capacitors in the core and leakage path are established, and a simulation jig is devised to link the physical model and the electrical terminal characteristics with an automated parameter determination process. The derived formula is verified by measurement results of the prototype transformer samples. Given its accuracy and simplicity, this approach is suitable for analyzing and designing LLC resonant transformers whose leakage and magnetizing inductance are very critical to circuit operation.
