Many of the existing methods of dielectric characterization measurement are based on small signal measurement. Through those methods, some important information, such as dielectric constant at different voltages, a critical concern for integrating passive modules, cannot be obtained. This paper presents a new method to measure dielectric characterization under resonant and constant current conditions for ranges up to 850 V and 10 A. With this circuit, the characteristics of dielectric materials under representative large signal renditions and time down to 1 μs can be found
