Abstract From the Canadian patent

The DC/DC converter with an output current which is periodically variable over time comprises a control network (11) which generates a variable reference signal, (RefI) for the input current which is substantially smoothed and obtained from the, difference between the output voltage (V out) and a reference voltage (V ref). The, substantially smoothed reference signal (RefI) causes a variation on the duty cycle of, the converter in order to compensate for the variation in the output voltage (V out), resulting from a variation in the output current (I out).

Why it's free to use

  • Filed June 16, 2003. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 16, 2023.
