10 A power supply - for wide range of output voltages

10 A power supply Power supplies with an output rating of over 300 W, as needed, for instance, in computer systems, multiple disk drives, radio transmitter/receiver installations, and the like, can be pretty expensive. Fortunately, with the advent of voltage regulator ICs, it has become possible to build such a supply yourself at a much lower cost: without going into computations, we reckon that a saving of about fifty per cent can be made. for wide range of output voltages The power supply proposed offers the possibility of an output voltage (fixed) between 1.2 and 32 V at a current of 10 A. The output voltage depends, of course, on the transformer rating. The voltage regu- lator ICs have on-chip current limiting, so that, given correct and careful assembly, the unit will give long and reliable oper- ation. The design includes a printed cir- cuit board to facilitate construction. Circuit description The circuit of the proposed unit consists basically of a generating part and a re...
