| Abstract |
As part of its research into ozone production, EDF’s Research and Development Division needed a
power supply to enable testing of different waveforms. This resulted in the signing of a contract with
CIRTEM for development of a high-voltage test amplifier.
This amplifier, controlled by a programmable signal generator, is capable of generating a wide range
of waveforms (sinusoidal, triangular, square, pulse, plus a possible DC component) at different
frequencies.
To comply with the technical specifications, the amplifier developed by CIRTEM comprises 16
inverters in series. The control law for the inverters enables multi-level pulse width modulation
(PWM). |
