High-accuracy pulse/direct current digital power of ionic accelerator

Abstract

The invention relates to a high-accuracy pulse / direct current chopping digital power of an ionic accelerator, which comprises an ionic accelerator high-accuracy general digital power regulator, an ionic accelerator general digital power controller, a low-voltage transformer, a three-phase diode rectifying and filtering circuit, an H bridge bidirectional chopping circuit, a high-accuracy current feedback circuit and a load circuit. By using the ionic accelerator high-accuracy general digital power regulator to control and regulate a chopping-type non-isolating switch circuit, a high-accuracy digital power of the ionic accelerator which can work in two operating modes, namely, a pulse operating mode and a direct current operating mode, is realized, and the requirements of the digital power of the ionic accelerator in terms of high-accuracy data acquisition, high-speed and high-accuracy digital regulation, high-accuracy PWM output and the like are satisfied. The high-accuracy pulse / direct current chopping digital power has simple and reliable operation mode, can realize communication and operation to the digital power by means of a local human-computer interface and can also realize remote network control to one or more digital powers by utilizing a CAN bus networking method. The high-accuracy pulse / DC chopping digital power can be applied to ordinary ionic accelerators and special ionic cancer-treating accelerators, or other similar applications.
