Power semiconductor device IGBT is related to the reliability of power module, so it necessary obtain accurate junction temperature. In this paper, an electrothermal model established based on theory analogy. The methods interpolation, curve fitting and cyclic iteration are used build model, temperature module under different input conditions can be obtained. We also use evaluate efficiency water cooling. not only estimate accurately, but assist heat sink design, which helps improve has...
High Intensity heavy ion Accelerator Facility (HIAF) aims to provide beams with the highest pulse beam intensity in world, and BRing (Booster Ring) is its main accelerator. Therefore, HIAF-BRing dipole magnet power supply needs output fast, high-precision large current wide range of high voltage. Not only that, also meet requirement long-term stable operation. These requirements mean that structure reliability design are very important. In order these requirements, project team proposes a...
The High Intensity Heavy-ion Accelerator Facility (HIAF) places high demands on the magnet power supply. In order to solve its special requirements, especially tracking accuracy, Analytic Modeling Optimal Control (AMOC) is proposed. To get most suitable model of supply, natural discreteness and continuity are considered discussed in detail by comparing with other modeling methods. addition, AMOC decomposes supply control problem into a sing-cycle optimization problem. Compared PI regulation,...
To obtain higher accelerator beam quality and operating efficiency, the performance of power supply system often plays an important role. In view continuous updating electronic devices requirements integration miniaturization, electromagnetic interference is becoming more serious. Strong will affect stable operation other sensitive systems system, even reduce quality. this paper, transient response switching points studied, including surge ringing. Through calculation experimental...
