Based on the analysis of operation principles of conventional self-exciting electronic ballast, the cause of high switching loss has been researched. In order to reduce switch temperature and increase the reliability of the whole circuit, drive circuit of self-exciting electronic ballast has been improved to achieve soft switch. Circuit simulations and experimental results are coincided with th...

The incompressibility constraint makes Navier-Stokes equations difficult. A reformulation to a better posed problem is needed before solving it numerically. The sequential regularization method (SRM) is a reformulation which combines the penalty method with a stabilization method in the context of constrained dynamical systems and has the benefit of both methods. In the paper, we study the exis...

The zero-potential scanning circuit is widely used as read-out circuit for resistive sensor arrays because it removes a well known problem: crosstalk current. The zero-potential scanning circuit can be divided into two groups based on type of row drivers. One type is a row driver using digital buffers. It can be easily implemented because of its simple structure, but we found that it can cause ...

Permanent Magnet Brushless DC Motor has become a popular electrical drive because of its advantages such as high efficiency, increased reliability, quick dynamic response and very low maintenance. Due to this competitive edge it has stirred a lot of interest in simulating a PMBLDC Motor and its associated drive system in a comparatively simple manner. This paper elaborates the proposal of devel...

Systematic Review methodology (SRm) is an increasingly popular choice for literature reviews in the Social Sciences. Although, compared to traditional narrative reviews SRm appears timeconsuming and laborious, transparency and replicability of the methodology is argued to facilitate greater clarity of review. Nevertheless, researchers in Industrial, Work and Organizational (IWO) Psychology have...
