Product Topology
The SynQor MPC-1500 Series products use a true on-line double conversion topology that
provides protection to the load from spikes, noise, surges, brownouts, blackouts, etc. in the
input power sources. They also provide smoothing of load transients and nonlinear load
profiles so that the input power sources are not subjected to these disturbances. There is
a seamless transfer from any power source to another so that there is no disruption in the
output voltage waveform.
As the figure below shows, there is a nominal 28 V mid-bus within the MPC that draws power
from one of up to two power sources: the AC INPUT, or the optional DC INPUT (with that order
of priority based on availability). EMI filters are present at all external inputs and outputs.
