| Abstract | An apparatus for estimating the remaining life of a power converter (11) comprises a current sampling unit (13) which samples the switching current signal at a capacitor (5,6) of the power converter (11), a voltage sampling unit (10) which samples a ripple voltage at the capacitor (5,6), a temperature sensing unit (14) which senses a temperature at the capacitor (5,6), a timer unit (15) which tracks the operation time of the power converter (11), and a computation unit (17) which estimate the remaining life based on the output signals from the current sampling unit (13), the voltage sampling unit (10), the temperature sensing unit (14) and the timer unit (15). A corresponding method is also provided. |
