Abstract

Temperature field measurement is an important step in the design of grid-connected filter reactor

which requires the fundamental current passed reactor to be controllable

the switching frequency of ripple to be adjustable

the power losses to be reduced as much as possible and higher requirement for the test power of temperature filed is put forward.Therefore

kind of a power device with energy feedback for temperature field measurement is designed.Based on the main circuit topology of back-to-back PWM converter

the control proposal for the test power is analyzed deeply

the relationship among the control parameters of converter controller

the inductance of the tested reactor and switching frequency is given so to provide online correction for the controller parameter and achieve temperature field test of grid filter at different capacitance or different switching frequency.Meanwhile

the mathematical model between input & output current of the tested power and grid side current is set up so to provide evidence for the energy saving assessment of the energy feedback test method.Finally

the experimental system of testing power is set up and the correctness of the theoretical analysis is analyzed by its result.
