* 1 Thermal efficiency: The percentage of thermal energy that is converted into electricity or work. For example, when thermal energy input is 100 and the work done is 50, the thermal efficiency is 50%. The rest of the energy is converted into other forms of energy such as heat, which is called loss. The thermal efficiency can never exceed 100% or never be 100%.

* 2 Derating: A technique in which devices are operated at less than their rated maximum power or operated by reducing the power dissipation and operating voltage, taking into account the operating temperature and design life.

Future Plans

We will actively promote and sell SynQor products to our existing customers in the military, satellite, and industrial equipment markets as well as to new customers in the rail, medical, and communications equipment markets.
