Frequently Asked Questions
Alta’s rectifiers are designed as part of integrated electrification systems, optimised for high power, continuous operation, and demanding environments rather than standalone industrial use.
Yes. Power rating, cooling method, control integration, and electrical characteristics can be configured to suit specific applications and system architectures.
Yes. Rectifiers can be integrated within regenerative braking architectures, enabling recovered energy to be stored in batteries or redistributed within the system.
Converting Power for
High-Demand Systems
Alta’s AC–DC rectifiers convert alternating current into stable direct current for use in high-demand electrification systems. Designed for industrial, rail, and heavy mobility applications, they form a critical part of traction power systems, charging infrastructure, and energy management architectures.
Beyond basic conversion, Alta’s rectifiers are engineered to deliver reliable, high-quality DC power under fluctuating loads, harsh operating conditions, and continuous duty cycles. Each system is configured to suit the specific electrical, thermal, and control requirements of the application.
They are commonly deployed in

Traction power systems for
locomotives and shunters

Charging systems for battery-electric and hybrid vehicles

Battery energy storage systems operating on grid, off-grid, or hybrid inputs


Regenerative braking architectures, enabling
energy to be recovered
