- Summary
-
The design and performance of an experimental dc-dc converter are described. The converter was rated for a power output of 1 kW, with a 150-percent overload rating, and it produced a 200-V, +1-percent, dc output from an input of 56 V, +10 and -20 percent. Voltage regulation is accomplished by varying the duty cycle of the internal 7-kHz quasi-square-wave carrier. Integrated circuits in the control section, a proportional current drive system, and powdered metal cores (Ni-17Fe-2Mo) for the power transformer were some of the design features. The measured efficiency peaked at 92 percent and was 88 percent at 1 kW. The total component weight was 6 lb (2.7 kg).
