Abstract
AbstractThis paper aims at designing a small size, light weight high-frequency high-voltage (HFHV) pulse power supply for cable fault detection, achieving integration of cable fault detection system. The 3.5 kW/35 kVpulse power supply adopts series-parallel resonant converter topology to compensate the distributed parameter. Both the switching frequency and the duty cycle are utilised as actuating variables to cope with the large ranges of output, by this method the switch and anti-parallel diode can achieve soft switching within a small range of switching frequency adjustment 18 to 25 kHz. Furthermore, segmental-data-processing method is proposed in this paper, by this method multiple different steady-state operating points can be obtained to cope with different load which improves the efficiency and stability of the system effectively. Through theoretical analysis and large number of experiments, the structure of the HFHV transformer is optimised. Some special methods are taken to strengthen insulation ...
