2. General
The real-time simulation technology is widely used in the power system. Different digital
simulation system are developed such as RTDS, EDF and TEQSIM, etc. But no matter how
the digital simulation or digital-analog model simulation changes, the power amplifiers are
the main component in the system.
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.
PA460Bi-L amplifier
is specially designed for power electricity simulation and solves the
high power problem for linear power amplifier and accuracy problem for heavy current
output.
PA460Bi-L amplifier
has six-phase current output. Each phase maximally outputs 15A
RMS and maximum output power of 135VA. There is six-phase voltage output. Each phase
outputs 120V RMS and maximum output power of 60VA.
