Product Topology
The SynQor MINV-4000 Series products use an isolated 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 source
is not subjected to these disturbances.
EMI filters are present at all external inputs and outputs.
Power flows from the DC INPUT through an isolated DC-DC converter. The AC OUTPUT is created
by an inverter that draws power from the mid-bus. The inverter provides high-frequency safety
isolation and a pure-sinusoidal output voltage waveform. An optional electronic breaker can be
added to the AC OUTPUT. This one pole hot side only electronic breaker allows for fault-tolerant,
glitch-free operation when several MINV units are placed in parallel.
Bulk energy storage capacitors are connected to the mid-bus to help smooth imbalances in
power flow between the inputs and outputs of the MINV.
There is a communication/control port that provides a digital interface to a host computer system.
