A new domestic voltage regulation system for aviation has been developed at Novosibirsk State Technical University (NSTU), which is a universal unit for aircraft. This device was created as part of the "Priority 2030" program and significantly surpasses domestic counterparts in a number of characteristics.
The main feature of the development is the use of domestic SiC transistors (silicon carbide transistors) and digital control. The new unit is designed to normalize the voltage in the aircraft's onboard network, which can be unstable due to the operation of electric generators driven by gas turbine engines. The device regulates the voltage, preventing surges and various malfunctions, such as short circuits or overheating.
In addition to protection, the new unit also performs monitoring and data transmission functions to the aircraft's information system, including the black box. The device is significantly reduced in size and weight, while its assembly time is reduced by 1.5 times, and its performance is improved. It can work with a wide range of aviation generators, from 16 to 250 kW, which allows it to be used for both serial and promising generator models.
The development has already attracted the interest of aviation companies and may be installed on domestic, as well as foreign aircraft, such as Boeing and Airbus. In 2025, it is planned to release a pilot batch of products, and in the future it will be mass-produced at the microelectronic technology plant in Izhevsk with delivery to the Sarapul Electric Generator Plant (SEGZ) and other customers.
