Abstract
The invention relates to a method for measuring a current or voltage output quantity of a switched-mode power supply circuit (H), referred to as a chopper circuit, of period T and of cyclic ratio α, belonging to the interval]0; 1[, such that, at each period, the supply current is non-zero during an 'ON' phase of duration αT, and zero during an 'OFF' phase of duration (1−α)T. The measurement method includes the following steps: measuring the value Gof an image of the output quantity during an “ON” phase; measuring the value Gof an image of the output quantity during an “OFF” phase; calculating the difference ΔG=G−G; and using the difference ΔG for evaluating the output quantity.
