A new method of real-time supervision for insulation of DC system is adopted in this paper,which uses double asymmetrical bridge in normal mode.

Generally unbalanced degree of symmetrical bridge is used as a chief means for reflecting insulation of DC bus,however it becomes disabled when insulation of positive and negative poles of DC bus drops in the same proportion.

Novel asymmetrical half-bridge ZCS arc welding inverter power;

Research of Single-Stage PFC Converter with Asymmetrical Half-Bridge and Current-Doubler Rectifier;

An asymmetrical half-bridge operation in soft switching mode can reduce switching power loss and improve the efficiency of power supply.

This paper analyzed the deflection and displacement of the large span asymmetric bridges during the construction and using,and introduced detailed method about how to calculate the elevation of the moulding boards set method,which can be used to guide the construction.

The asymmetrical half bridge converter is the critical part of computer switching power supply, it is the place where to bring in the passive soft-switching technology, so the aim of this paper is to bring the simple and effective passive soft-switching techn.
