| Abstract |
This paper describes the development of a novel
three-phase phase-locked loop (PLL) used to compensate for
mains variations by being incorporated as part of a
feedforward loop in a three-phase telecommunications
power converter. A telecommunications converter must
comply with industry standards, in particular the
psophometric noise standard CCIF-1951; this is achieved by
controlling the output voltage ripple from the dc-dc
converter. It is required that psophometric compliance is
maintained under expected mains variations documented in
the EN50160 power quality standard. The software PLL is
simulated and performance characteristics show a high
degree of noise rejection while also maintaining good
dynamic performance. |
