==Electronic Device with Frequency Dithering - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18341474 titled 'Electronic Device with Frequency Dithering

==Simplified Explanation==

- An electronic device with an inverter that converts DC power to AC power using a clock signal at a given frequency.
- The inverter receives a dithered clock signal that is frequency dithered using a modulating signal.
- The dithered clock signal has at least three different frequency levels during a repeated cycle of the modulating signal: a fundamental frequency, a lower first frequency, and a higher second frequency.
- The dithered clock signal is at the fundamental frequency for fewer total periods than at the first frequency and the second frequency during the repeated cycle of the modulating signal.

== Potential Applications ==
- Power electronics
- Renewable energy systems
- Uninterruptible power supplies

== Problems Solved ==
- Efficient conversion of DC to AC power
- Improved power quality
- Reduced electromagnetic interference

== Benefits ==
- Higher efficiency in power conversion
- Enhanced performance in electronic devices
- Increased reliability in power supply systems


==Original Abstract Submitted==

An electronic device may include an inverter. The inverter may convert direct current (DC) power to alternating current (AC) power. The inverter may use a clock signal at a given frequency to output corresponding alternating current signals at the given frequency. The inverter may receive a dithered clock signal that is frequency dithered using a modulating signal. The dithered clock signal may have at least three different frequency levels during a repeated cycle of the modulating signal. The at least three different frequency levels may include a fundamental frequency, a first frequency that is lower than the fundamental frequency, and a second frequency that is higher than the fundamental frequency. The dithered clock signal may be, during the repeated cycle of the modulating signal, at the fundamental frequency for fewer total periods than at the first frequency and for fewer total periods than at the second frequency.
