  • Current measurement for an electric heater
    Patent number: 9429596
    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 ?, belonging to the interval]0; 1[, such that, at each period, the supply current is non-zero during an “ON” phase of duration ?T, and zero during an “OFF” phase of duration (1??)T. The measurement method includes the following steps: measuring the value Gon of an image of the output quantity during an “ON” phase; measuring the value Goff of an image of the output quantity during an “OFF” phase; calculating the difference ?G=Gon?Goff; and using the difference ?G for evaluating the output quantity.
