Abstract :
A novel circuit is proposed to implement reflex charging for rechargeable batteries. The required asymmetrical bilateral pulses for reflex charging are generated controlling the only one active power switch with pulse-width-modulation (PWM) control. The pulse width of the charging current is regulated simply by controlling the duty ratio of the active power switch, while the amplitude and duration of the negative impulse can be determined by the designed circuit parameters. Experimental tests are carried out to verify the theoretical analyses.
