2. General
Real time digital simulator technology has broad applications in power system test and
research nowadays. As the computer technology and the research of power system
simulator are improving, several different kinds of digital simulator systems are coming out
continuously, such as RTDS, EDF, TEQSIM, etc. However, power amplifier, as the final
output in the simulator system, will always be the most important part of full digital simulator
or digital-analog simulator, no matter how they have changed.
The power amplifier for digital simulator in power system is required to have high linearity,
quick response, be available to all kinds of capacitive, inductive and resistive loads.
Generally power amplifier consists of two types of amplifiers: linear power amplifier and
switching power amplifier. The linear power amplifier has the strengths of high linearity,
quick response, high accuracy, good electromagnetic compatibility and the weakness of
bad performance in high current and high power cases. The switching power amplifier is
quite fit in high current, high power devices with its strength of high efficiency, but it’s weak
in linearity, small signal noise, DC offset, drift, transient response, load driving capability
aspects, which are very difficult to fix.
PAC2000B is a kind of high performance linear power amplifier specially developed for
power system simulation, showing incredible performance of not only solving the accuracy
problem for linear power amplifier during high power and high current output but still
keeping the strength of being available for all kinds of capacitive and inductive loads.
The dual supply amplifier system composed by PAC2000B can produce 6-phase current,
with maximum RMS phase current of 200A and maximum output power of 5000VA.
