At
this time of the power electronic technology has been able to realize rectifier
and
inverter with charger
, but working frequency is low, limited in the low-frequency range.
1.3 inverter with charger era
Into the eighty s, large scale and very
large scale integrated circuit technology rapid development, laid the groundwork
for the development of modern power electronic technology.
Will fine processing technology of
integrated circuit technology and the high voltage large current technology
organic union, appeared a batch of new type of all control power device, the
first is the advent of power M0SFET, led to the small and medium-sized power to
the development of high frequency power supply, then the insulated gate bipolar
transistor (IGBT), and for large and medium-sized development brings
opportunities to high frequency power supply.
Thereafter, MOSFET and IGBT of power
electronics is the traditional to the modern
power inverter
transformation.
According to statistics, by the end of 1995,
power M0SFET and GTR in power semiconductor devices on the market has reached
the point of vie, and replace GTR with IGBT have been established in the field
of power inverter.
New device not only provides the ac motor
frequency control of motor speed the development of high frequency, make the
performance more perfect and reliable, and makes the development of modern
electronic technology constantly to high frequency change, for efficient energy
saving, material saving of electrical equipment to achieve small, lightweight,
mechanical and electrical integration and intelligentization provides important
technical foundation.
2. The application field of modern
solar power inverter
2.1 computer efficient green power supply
Rapid development of computer technology to
lead the human into the information society, but also promoted the rapid
development of power technology.
In the eighty s, the computer fully used
the switching power supply, take the lead in complete computer solar power inverter.
Then switch power technology successively
in the electronic, electrical equipment.
