Rural living conditions (RLCs) in China are influential on the overall development and stability of regions, particularly for populations in distant poverty-stricken villages. This paper takes 16 villages of Chedao town in Gansu province, Northwest China (NWC) as our case study. Using data from the Poverty Alleviation and Assistance (PAA) project launched by Lanzhou University in June 2017, and the perceptions of residents of Chedao, we pinpoint RLC changes in the targeted poverty alleviation (TPA) process. The three main results show that: (1) From the residents’ perceptions, the impact of alleviation measures on RLC is mainly reflected in improved housing conditions, infrastructure, and public services. We find no significant effect on cultural conditions. However, eco-environmental conditions have obviously weakened. (2) Housing size, accessibility, distance to shops, and safe drinking water are the most significant factors in housing conditions, infrastructure, public services, and eco-environmental conditions, respectively. (3) Out of the different levels of rural poverty households (RPHs), severe rurality villages are more strongly aware of the positive changes in RLC than residents of mild rurality villages. Moreover, in residents’ view, housing conditions are most improved in severe rurality villages, infrastructure is most improved in moderate rurality villages, and public services are most improved in mild rurality villages. Eco-environmental conditions worsen across all levels. Our findings shed light on the perceptions of residents on changes occurring in rural living conditions, and provide a basis for subsequent studies of RLC in Northwest China.

“…The TMS pulse generating circuit is composed of a capacitor, a capacitor charging circuit, and an electrical switch that connects the capacitor to the coil [2, 3]. A special charging circuit for capacitor charging is commonly referred to as the capacitor charging power supply (CCPS) [4]. The significant difference between CCPS and traditional power supply is that it requires operation under a wide range of load conditions.…”

“…The capacitor charger which charges this capacitor bank is requisitely installed in each segment [2]- [4] where its high efficiency, high reliability, high power density, fast charging capability are simultaneously required. Although high power capacitor chargers have often been implemented through PWM topologies [5], [6], resonant topologies have been preferred to PWM topologies because the resonant topologies operate advantageously under various load conditions such as shorts or open circuit [7]- [9]. Among the various resonant topologies, the series resonant type topology which has a simple circuit, constant characteristic impedance and constant resonant frequency even in a wide range of load capacitances has been adopted more often for high voltage and high power capacitor chargers [10]- [14].…”

In this paper, the charging characteristics of series resonant type high voltage capacitor chargers considering the transformer stray capacitance have been studied. The principles of operation for the four operational modes and the mode changes for the four different switching frequency sections are explained and analyzed in the range of switching frequency below the resonant frequency. It is confirmed that the average charging currents derived from the above analysis results have non-linear characteristics in each of the four modes. The resonant current, resonant voltage, charging current, and charging time of this capacitor charger as variations of the switching frequency, series parallel capacitance ratio (k=C p /C s ), and output voltage are calculated. From the calculation results, the advantages and disadvantages arising from the parallel connection of this stray capacitance are described. Some methods to minimize charging time of this capacitor charger are suggested. In addition, the results of a comparative test using two transformers whose stray capacitances are different are described. A 1.8 kJ/s prototype capacitor charger is assembled with a TI28335 DSP controller and a 40 kJ, 7 kV capacitor. The analysis results are verified by the experiment.
