연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Abstract ▼ AI-Helper 아이콘AI-Helper

This paper presents the performance and efficiency of a drive system incorporating a switched-reluctance motor (SRM) with input power factor correction (PFC). The proposed system consists of a PFC, bi-directional converter, an inverter, and a SRM operating as based voltage source drives (VSD). First...

제안 방법

  • Operational modes of the proposed VSD systems have been identified and analytical derivations are made for each mode. Based on this, the system equations and design procedures are systematically derived to evaluate the drive system performances with and without an input PFC pre-regulator. A comparison of drive performance with input PFC shows its overall system efficiency is consistently lower than that without an input PFC.
  • In home applications, VSDs are likely to enter the market due to high efficiency and energy-saving aspects. In this paper, the proposed system consi아s of four different functional modules: an input module which includes a diode bridge rectifier, a charger and discharger module implemented by a conventional buck/boost scheme, a battery module and an inverter based SRM drive module. The ratings of the converter are based on the analysis for a given SRM capacity.
  • The experimental results are focused on the functioning of the bi-directional converter system, proper operation of the charger and discharger modules. Fig.
  • 4. The proposed bi-directional converter consists of four different functional modules: an input module which includes a diode bridge rectifier and PFC prereg나lator, a charger and discharger module implemented by a conventional buck/boost scheme, a battery module and a C-dump converter based SRM drive module'이. Note that the charger unit, which is implemented with the buck topology, comes in both versions - with and without the PFC preregulator.

대상 데이터

  • The C-dump converter for the SRM drive is MOSFET-based. The charger is built using an IGBT switch and tested with and without a PFC, The battery module consists of four series connected, sealed, lead-acid rechargeable batteries; each having a 12V and 7Ah rating. A permanent-magnet brush de generator with a resistive bank serves as the load for the SRMdrive system.
  • 8. The proposed SRM drive system consists of a C-dump converter, which is shown, in Fig. 5, and a three phase SRM with an 8-bit absolute encoder. The control circuit of the C-dump consists of the main and auxiliary PWM controllers, This section is concerned with the design procedures of PI speed and current control circuits for the VSD system.

이론/모형

  • 11. All system simulations are performed in Matlab-Simulink. Fig.
  • The Matlab-Simulink package was used to simulate the proposed system. Simulation of the motor was based on equations 10 and 13 and on the tables of torque as functions of angle and c나rrent, and current as a function of angle and flux linkage.
