The efficiency, power quality, and reliability of renewable energy power conversion systems are key factors for future industrial applications. This paper presents a novel scheme to improve the performances of high-voltage large-capacity photovoltaic (PV) power stations. The power conversion of the PV system is divided into two stages, i.e., dc/dc power(More)
In an electric vehicle power system, a step-up converter is required to increase the voltage from 24 V to 270 V. To achieve such a high voltage boost ratio, there are several challenges that must be overcome: tackling the leakage inductance of the isolation transformer; reducing the voltage stress on the power switches; and guaranteeing fast dynamic(More)
The high negative voltage power supply for the ECRH(Electron Cyclotron Resonance Heating) is a key component of the cyclotron. This system is the nonlinear system with the high requirements on static and dynamic performance. It is difficult to control well using traditional PID controller, so a new intelligent method is adopted to turn PID parameters base(More)
