Abstract :
Submarine lead-acid batteries need high current, low voltage battery chargers with high DC stability and high dynamic response at low level ripple. A buck type phase shift pulse-width modulated switching quasi-resonant converter is presented in this paper. Switching principles and operation modes of the proposed system are described with design based analysis. The experimental results of a 8kA, 10V modular converter are presented to verify the feasibility of the proposed system.
