  In this work, we study multicomponent dark sectors comprised of a fermionic
and a scalar dark matter candidate. In the scalar sector, we mostly focus on
the Inert Doublet Model while in the fermionic sector we study three different
models. For all of them, we investigate the impact that dark matter conversion
and regular WIMP dark matter annihilating processes have on the relic
abundance. We mostly recover the region between the electroweak scale and
$\sim$ 550 GeV for the scalar dark matter mass, which is usually excluded in
the Inert Doublet Model. We also consider current constraints from both direct
detection and indirect detection experiments and include future prospects to
probe the models. Additionally, we investigate constraints from collider
searches on the fermionic dark matter candidates.
