Abstract

The application of power electronics technology has penetrated into the national economic construction, transportation, space technology, the modernization of national defense, medical, environmental protection and people in all areas of daily life. After entering the new century electric power electronic technology is used more and more widely. Take the computer as the core information science will be twenty-first Century played a dominant role in the science and technology one, somebody is fatidical, power electronics and motion control and computer technology together, will become the two pillars of the future science.

The power electronic technology is applied in power electronics technology. Specifically, is the use of power electronic devices for power conversion and control technology. Usually the power electronic technology is divided into power electronics manufacturing technology and variable flow technology in the two branch.

Converter technology is also known as the application of power electronic devices technology, it involves the use of power electronic devices of various electric power conversion circuit and the circuit control technology, as well as by the circuit circuit, electronic device and power electronic systems technology. " Flow" refers not only to the exchange between the AC and DC, including DC DC and AC AC converter. If there is no thyristor and power transistors and power electronic devices, there is no power electronic technology, power electronic technology is mainly used for power converter. It can therefore be considered, the power electronic device manufacturing technology is the power of electronic technology foundation, and converter technology is the core of power electronic technology. Manufacture technique of power electronic device is based on the theory of semiconductor physics, and converter technology is based on the theory of circuit theory.

Changing DC into AC circuit called the inverter circuit, according to current use can be divided into active and passive inverter inverter.

This course is designed to introduce a single-phase half-bridge passive inverter circuit.

Key words: passive inverter, rectifier, thyristor
