A hybrid power system, whose heart is the innovative Starter-Generator (SGM - Starter-Generator Module), provides a reliable source of energy for modern combat vehicles.
The system is built around a 750 VDC bus generated by a Starter-Generator controlled by a dedicated inverter. This energy feeds key vehicle subsystems such as the air-conditioning compressor and engine cooling fans and —via bidirectional DC/DC converters—the low-voltage (28 VDC) systems. The low-voltage rail charges the onboard batteries, ensuring a stable and safe supply for all onboard equipment.
Crew safety is a primary design focus: there is no high-voltage traction battery, which significantly reduces hazards associated with storing large amounts of electrical energy. The high-voltage domain (750 VDC) is confined to the engine compartment; within the crew space only the safe 28 VDC rail is present. Additionally, the system can be equipped with a supercapacitor module that, through the bidirectional converters, stores the energy required for instant engine start-up.
What is a Starter-Generator?
The Starter-Generator (SGM) is an integrated unit with a dual role: it first acts as a starter to crank the internal combustion engine, then operates as a generator to produce electrical power for all vehicle systems. Thanks to its construction, the SGM offers high reliability, fast starts, and efficient electrical power generation. SGM-based hybrid system — offers advantages that distinguish it from competing solutions available on the market:
Versatile Applications
The SGM power system is well-suited to a wide range of military applications:
The configuration described above is an example for a land platform. Radiotechnika Marketing can tailor the system to the specific requirements of a given application.
