Abstract
Among other things, one or more techniques and/or systems are described for reducing a voltage ripple in an electric signal. In this way, in radiographic imaging modalities, for example, undesired fluctuations in an output of a radiation source (e.g., undesirable fluctuations in an energy level of emitted photons) may be reduced. To reduce the voltage ripple, a (ripple reducing) electric signal is generated that comprises properties substantially similar to the voltage ripple, but opposite in phase. The (ripple reducing) electric signal is then combined with the original electric signal to generate a combined electric signal with a voltage ripple that is reduced relative to the voltage ripple of the electric signal as initially generated.

A system for reducing fluctuation in an output of a radiation source of an imaging modality, comprising:
- a waveform control component configured to:
- receive information regarding a desired voltage to be applied to the radiation source;
- determine a desired property of a second electric signal, generated by a waveform generator component, based upon the information;
- and
- notify the waveform generator component of the desired property;
- the waveform generator component configured to:
- generate the second electric signal, the second electric signal having the desired property and combined with a first electric signal generated by a power supply component to yield a combined electric signal having a reduced voltage ripple relative to a voltage ripple of the first electric signal, the combined electric signal input into the radiation source;
- and
- a transformer circuit configured to electrically isolate the waveform generator component from the first electric signal, the second electric signal transmitted through the transformer circuit prior to being combined with the first electric signal.
A method for reducing voltage ripple, comprising:
- receiving information regarding a desired voltage to be applied to a radiation source;
- comparing the information to information comprised within a lookup table to determine a desired property of a second electric signal;
- generating the second electric signal based upon the desired property;
- combining the second electric signal with a first electric signal to yield a combined electric signal having a reduced voltage ripple relative to a voltage ripple of the first electric signal;
- and
- inputting the combined electrical signal into the radiation source.
