Dielectric Charge-Discharge Test System focuses on evaluating the high-voltage discharge performance of dielectric energy storage materials. Conventional methods, which calculate energy density from hysteresis loops, have limitations: during testing, the charge from the sample flows back to the high-voltage source rather than to an actual load. This results in hysteresis loop-derived energy storage density values that are often higher than the actual energy density released by the material, failing to accurately assess its discharge performance.
The GoGo Instruments Dielectric Charge-Discharge Test System is specifically designed to address the above challenges. It is used to study the rapid charge-discharge characteristics of energy storage dielectric materials (e.g., ceramics, thin films, etc.). Its core advantage lies in its ability to simulate real discharge scenarios and support underdamped and overdamped charge-discharge tests under variable temperature conditions, making it a key scientific research tool in the field of energy storage materials.
1、The system employs a specialized high-voltage switch utilizing a single-pole double-throw (SPDT) mechanism to control charging and discharging processes. The switch withstands up to 10 kV, featuring low parasitic capacitance and short switching time.
2、Maximum voltage: 10 kV; maximum current: 5 mA.
3、Discharge current is measured via a current probe, with a maximum measurable current of 100 A.
4、Supports both underdamped and overdamped testing modes:
In underdamped mode, the discharge circuit is short-circuited without a resistive load.
In overdamped mode, a large, high-precision non-inductive resistor is used as the discharge load.
5、Data acquisition is performed via an oscilloscope, with direct calculation of energy storage density.
6、Custom-designed sample holder compatible with both ceramic and thin-film specimens.
7、Variable-temperature testing capability from room temperature (RT) to 200°C.
8、Supports fatigue testing.
