DC to AC
Inverter
Controlling AC Power
for Electrified Systems
Alta’s DC–AC inverters convert direct current into controlled alternating current for use in high-demand electrification systems. They are a core component in traction, energy storage, and industrial power architectures, enabling DC energy from batteries or generators to drive AC motors and interface with AC systems.
Designed for continuous operation in demanding environments, Alta’s inverters deliver precise control over voltage, frequency, and power output. Each inverter is engineered as part of a broader system, optimised for performance, efficiency, and integration rather than standalone use.
They are commonly used in:
Traction motor drive systems for locomotives and heavy mobility equipment
Battery energy storage systems supplying AC loads
Grid-connected and
off-grid power systems
Regenerative braking architectures, enabling
energy to be recovered

Frequently Asked Questions
During braking, traction motors operate as generators, producing AC power. Alta’s inverters manage the conversion of this energy into DC for storage or redistribution within the system, improving overall efficiency.
Alta’s inverter solutions can be configured across a wide power range, from auxiliary systems through to high-power traction applications, depending on system requirements.
Alta employs advanced thermal management strategies, including liquid cooling and intelligent control of cooling capacity, to maintain stable operation under continuous high loads.
