A DC-DC power converter cell is disclosed which incorporates novel control circuits that operates the cell at efficiencies of 88%. This cell also has control-in and control-out terminals whereby multiple cells are intercoupled to operate in synchronization with each other as a versatile system of cells. Manufacturing cost is reduced by utilizing a simply configured single-turn high-frequency transformer in each cell, and by operating at efficiencies that reduce cooling requirements.
