An improved single-ended push–pull (SEPP) halfbridge type zero-voltage soft-switching pulse width modulation (ZVS-PWM) DC–DC power converter is presented in this paper, which makes use of a saturable reactor-assisted lossless capacitor type zero voltage soft-switching method. The SEPP power converter with a high-frequency forward and flyback hybrid transformer link has some advantages such as l...

Conventional energy sources are fast depleting due to poor conservation practises and excessive usage while the world’s energy demands are growing by minute. Additionally, the cost of producing conventional energy is rising also leading to an increase in harmful environmental pollution. Hence, there is a need to look at alternative energy sources such as sun, water and wind. Photovoltaic (PV) i...

The theory of Soft power can be applied to the ruling party of social governance. At present, the Chinese Communist Party is facing political corruption, the public lack of political trust in the officials, social injustice and other social issues. It is necessary to construct the party's soft power and consolidate the party's ruling position.

Queueing soft hando attempts in DS-CDMA cellular systems can cause di erent e ects on system performance, compared with the hando attempts in TDMA and FDMA systems. This is because CDMA link capacity depends on other user interference which includes the power of blocked soft hando attempts. The power level of blocked soft hando attempts may be large because it cannot be controlled by a target b...

the main purpose of this paper is to introduce and study new classes of soft closed sets like soft regular generalized b-closed sets in soft topological spaces (brie y soft rgb-closed set) moreover, soft rg-closed, soft gpr-closed, soft gb-closed, soft gsp-closed, soft g-closed, soft gb-closed, and soft sgb-closed sets in soft topological spaces are introduced in this paper and we investigat...
