Description of Requirement:
A German university has developed a new digital power factor correction (PFC) that significantly reduces electromagnetic interference in power electronics systems. In addition, the hardware cost of passive filters or shielded enclosures can be reduced. Seek a licensee.
Technical cooperation agreements are also available.
details:
For devices powered by a mains (such as computer power supplies), regulate the current draw from the power supply. This is done through Power Factor Correction (PFC). Problem: There may be significant reactive and distorted power or spurious emissions that can interfere with nearby equipment, such as radios or routers. Often, these spurious emissions are limited by passive filters and shields, but they are expensive and bulky.
A German university has developed a method to selectively reduce spurious emissions by modulating anti-jamming signals. The anti-jamming synthesizer generates an anti-jamming signal from the synthesized and modulated sinusoidal signal, the amplitude and phase of which are calculated using the Fourier transform. The changing duty cycle of the PFC is also considered. The anti-interference signal is coupled into the whole system through the injector. Depending on the methods and algorithms, digital signal processing hardware, such as FPGAs, DSPs, microcontrollers or specially designed ASICs, electromagnetically interfere and control the anti-interference synthesizer accordingly in an optimized manner.
The German university offers interested companies the opportunity to license and continue developing the technology with the inventor within a technical cooperation agreement. The present invention should be of particular interest to electronics manufacturers of various device chargers who can use the technology in their systems.
