[StarWars] Did Anakin get stronger after the fight with Obi-Wan on Mustafar?

I've been told Anakin's wounds (I.E. losing two legs and an arm) in his fight with Obi-Wan on mustafar weakened his ability to use the force.

If so, was Anakin at the peak of his power when he was defeated by Obi-Wan? or did Anakin become stronger during his time as Darth Vader? was Anakin in a weakened state when he fought Obi-Wan?

Anakin's maximum Force potential was lowered by his injuries on Mustafar.  Had he not suffered his dismemberment and horrific burns, then he had the potential to eventually be approximately twice as powerful as Sidious.  As it was, though, after Mustafar his maximum ceiling was approximately three quarters of Sidious's power.  

Keyword here is potential.  At the time of his duel on Mustafar, Anakin wasn't at his maximum power yet.  So after he was put in the suit, he continued to develop his Force abilities, and actually became stronger in the subsequent years.  But he would never be strong enough to challenge Sidious directly.  

As for his combat skills, being put in the suit made Vader less mobile, which meant his saber skills had to be adjusted.  He adapted a more power-oriented style, compared to the fast and mobile Djem So style he practiced pre-Mustafar.  His new style was still devastatingly effective in combat, though, as evidenced by the fact that he defeated so many Jedi in the Purge.
