Abstract: A ripple detection device and a ripple suppression device. The ripple detection device includes: a ripple sampling unit, at least two DC sampling units, and a digital signal processing unit; the ripple sampling unit outputs a first voltage signal at an output port of a non-isolated DC/DC bidirectional energy conversion unit to the digital signal processing unit; the DC sampling unit outputs a first DC signal in a second voltage signal at a connected port of the non-isolated DC/DC bidirectional energy conversion unit to the digital signal processing unit and blocks an AC signal in the second voltage signal to be output to the digital signal processing unit; the digital signal processing unit determines a ripple noise signal at the output port of the non-isolated DC/DC bidirectional energy conversion unit according to the first voltage signal and the first DC signal.
