He has made significant contributions to the field of electromagnetic interference (EMI) reduction and power conversion technologies. With a total of four patents to his name, Acker's work is recognized for its innovative approaches to complex electrical challenges.
Latest Patents
Among his latest patents is the "Predictive Active Filter for EMI Attenuation." This invention provides methods and apparatus for reducing electromagnetic interference in power conversion stages. The method involves determining an estimated ripple voltage or ripple current using a predictive model. It generates a ripple cancellation signal of opposite polarity to the estimated ripple voltage or current, compensating for distortions in the signal path. This signal is then injected into a power supply's line filter to effectively reduce ripple voltage.
Another notable patent is the "Method and Apparatus for Grid Impedance Detection." This invention monitors an AC line for impedance changes. The method includes superimposing a tone on an AC current coupled to the AC line, where the tone is at a higher frequency than the AC voltage waveform. By applying correlation over a sampled AC voltage waveform, the method generates a correlated signal to determine any changes in the characteristics of the signal.
