With an in-depth analysis of the conventional battery charging method and technical requirements of lead-acid battery in small wind power system, a three-stage intelligent charger oriented based on SG3525A was designed. Its main circuit was the push- pull isolation convert structure and the charge strategy was the three-stage approach of constant current, constant voltage and trickle charge to achieve the different stages of battery charging requirements. The experiment results showed that the charger could adapt to a wide range voltage of charging requests and achieve real-time monitoring charge state and status display besides protecting over-volt- age and over-current.
