Although the theory and relative technique realizing half bridge arc welding inverter is well developed now,there are still many problems need to be deeply researched during the production and realization.

Output capacity of IGBT half bridge inverter power source has been discussed and its expression has been developed in this paper.

A half bridge switching mode power supply(SMPS) based on PWM technology is introduced.

The DC- DC Converter Circuit of Half-bridge Resonance Based on B-SIT;

The combination of boost and half-bridge or/and full bridge current-fed DC-DC converter are widely used in UPS,fuel-cell systems in which the input voltage is much lower than the output voltage.

This paper presents a half-bridge switching power supply in which a intelligent intergraded chip named UC3825 is used.

The application of modified key-way attachment on semi-fixed bridge;

A Study on the Galvanothermy of V Type Semiconductor Bridge under Constant Current;

Measurement of semiconductor bridge plasma temperature using spectroscopic method;

Numerical Simulation and Experiment Study on Semiconductor Bridge Ignition;

This paper introduces the design from the branch watershed(Hubei-Chongqing boundary) of the backbone of Shanghai-Chengdu National Expressway to semi-slope bridge(Huandanlian Bridge) on expressway in Zhong County,and proposes some rough understandings for the design of semi-slope bridges in mountainous areas as a source of reference for.
