人工衛星用バス電圧制御器の発熱低減・過渡応答改善制御法

In the conventional bus voltage controller, the concentration of heat generation in a specified circuit has been an obstacle to miniaturization. In this paper, we describe the control algorithm and the experimental result of the direct and distributed switching control (DDSC) method devised to disperse the generation of heat. Additionally, to improve the transient response while reducing the steady state switching frequency, which can reduce the generation of heat, we investigated the application of a transient mode that temporarily speeds up the control cycle when load fluctuation is detected. We also report the calculation of the heat reduction effect that can be achieved by combining these methods.
