Military field-grade AC changer

1 December 2019 Power Electronics / Power Management

SynQor’s new MAC-4000 is a compact, military field-grade 3-phase to single-phase AC changer. This 4 kW/5 kVA phase/frequency AC changer is designed for the extreme environmental and demanding electrical conditions of military/aerospace applications.

The MAC-4000 accepts a 3-phase 440 Vrms AC input and converts it to a well-conditioned single-phase AC output using a two-stage isolated DC mid-bus topology. Options include a selection of output voltage (115 or 230 Vrms), output frequency (50, 60 or 400 Hz) and an electronic circuit breaker on the AC output that permits glitch-free, fault-tolerant parallel operation of up to 32 units in single-phase, split-phase and 3-phase configurations as well as (N+M) redundancy.

The MAC-4000 also has a floating output ground optional feature for air or sea crafts for MIL STD 1399-300B compliant applications that might require that feature. In addition, it is equipped with an Ethernet-SNMP module that allows real-time remote system monitoring with trap/email.

In addition to facilitating the change of AC output characteristics from an established AC input source, the MAC-4000 also tackles the difficult problem of unbalance loads on 3-phase systems in aircraft and ships. MIL STD 1399-300B requires that all the phase currents be balanced to within ±5% for ships and ±3% for submarines. The 3-phase MAC-4000 allows single-phase loads to appear at the power source as a clean, well behaved, nearly zero reactance balanced MIL STD 1399-300B compliant 3-phase load.
