In the so-called "hydrogen bomb" or fusion bomb, yes, there is energy released from the same reaction (hydrogen fusing to helium) as in the Sun.
However, many if not most atomic bombs are fission bombs that do not involve fusion. In a fission bomb, the nuclei of uranium atoms are split, converting some of their mass to energy.
All current fusion bombs include fission reactions to trigger the greater energy release from fusion. But most of the energy in very large fission-fusion bombs comes from a third-stage reaction: the fusion causes an exceptionally powerful fission reaction in a uranium shell around the bomb. This called a Teller-Ulam device or fission-fusion-fission bomb.
Stars like our sun and hydrogen bombs produce energy through nuclear fusion.
Nuclear fusion
Nuclear fusion, in which hydrogen-1 is fused into helium-4.
The sun is kept in equilibrium by the balancing forces of the outward pressure from the energy of the nuclear reaction of hydrogen into helium and the inward force of gravity. This state is called Main Sequence. However, the sun is not in perfect equilibrium because as the sun's core of hydrogen is depleted, the next layer out of hydrogen will begin undergoing a nuclear reaction, causing the sun to expand.
The sun is a star, and it is also a nuclear fusion reactor. It is fusing hydrogen into helium to create energy via what we call the proton-proton nuclear reaction. Our local star has been doing this for billions of years, and will continue to do so for billions more.
Hydrogen bombs use the same process of nuclear fusionthat powers the Sun.
