Diehl Static Inverters & Frequency Converters
Static Inverters & Frequency Converters
Static inverters are used to produce AC power from DC. The DC power in this case comes from batteries. The AC is produced by using power semiconductors to chop up the DC into something that approximates a sine curve.
EAI is pleased to represent two manufacturers of aviation static inverters - Diehl Aerospace GmbH and L-3 Communications/EUROATLAS. The larger Diehl units are used to supply AC power to critical equipment in cases where only battery (DC) power is available.

The term “static” is used to differentiate these devices from the old way of performing such tasks, before reliable and sufficiently powerful semiconductors came along. Then it meant using various forms of rotating machinery – motors, generators and alternators.
These are all single-phase devices. The EUROATLAS units are relatively inefficient with a power factor of 0.4 to 0.6, but that hardly matters since they are so small.
