Title: Estimating the output current of a switch mode power supply
Inventor: PIPER JOHAN
IPC: H03H19/00
Filed: 2006-07-07
Abstract: The output current OC of a switch mode power supply (SMPS) is estimated by sensing the current IP in a primary winding of a transformer 21, controlled by switch 31. The sensed current signal CS is averaged when current is flowing in the primary and then scaled using an estimate of the time when current discharges from the secondary to give an output current signal OCM. The average primary current may be scaled by multiplying it by a fraction of a total cycle period of the SMPS, during which the secondary is providing power to the output, indicated by timing signals T0, T1 that are sensed from the switch DRIVE signal, the current sense signal CS and a voltage signal VS which may come form an auxiliary transformer winding. The CS signal can be averaged over a time TO by a switch (fig 6,11) and a low pass filter (fig 6, 12) and scaled using the time T1 by operating switches (fig 6, 14,15) and a further filter (fig 6, 16). Filters may be a switched capacitor type (fig 12) and comprise series resistors (fig 13, R) that are time sliced by switches controlled by timing signals (fig 13, P1,P2).
