Abstract

A DC-DC power converter (100) that provides increased power density, reduced size, and reduced costs of manufacture. The DC-DC power converter (100) includes first and second input terminals (101, 102), a plurality of output terminals (116, 117), and at least one electrical element (108/109) connected to at least one of the first and second input terminals (101, 102). In the event a first voltage is applied across the first and second input terminals (101, 102), the electrical element (108/109) provides a second voltage having a value between the first voltage value and a reference voltage value. The DC-DC power converter (100) further includes a transformer (110) having a primary winding (111) and a secondary winding (112), and a switch assembly (103–107) operatively connected to the first input terminal (101), the second input terminal (102), the electrical element (108/109), and the transformer primary winding (111). In the event the first voltage is applied across the first and second input terminals (101, 102), the switch assembly (103–107) switchably applies the first, second, and reference voltages across the transformer primary winding (111) to generate at least one third v…
