Abstract :
A method of in situ test of a real time measurement system, RTMS, is presented. The method involves superposing a probing signal on one of the measurement signals of the RTMS, The RTMS is used in a control system of a series loaded resonant converter, SLRC. The power spectrum of a SLRC is specific, the energy is concentrated in narrow bands. The energy of the probing signal is then chosen for certain frequency bands not used by the SLRC. The evaluation of the measurement channel state can be made by identification based on simple frequency or correlation methods
