Description
Summary:Pulsed power supplies require high voltage prime power sources, typically in the range of hundreds to thousands of volts. This input may be supplied through various energy storage devices such as capacitor banks, lithium-ion batteries, or hybrid technologies. One challenge for evaluating these energy storage devices is to characterize them at the high impulse power levels experienced when integrated into a pulsed power supply. Such high power test loads exist but are expensive and often do not satisfy rise times often seen by pulsed power loads. This work presents the design and development of a test stand for energy storage device discharge characterization at voltages up to 1.2 kV for pulsed power applications. The Pulsed Discharge Test Stand (PDTS) can be configured to operate at different loading points via current limiting ceramic disc resistors. Insulated-gate bipolar transistors (IGBTs) are used to discharge the energy storage device and control both the pulse duration and repetition rate. Operation of the pulsed discharge test stand is demonstrated up to 1 kV and up to 9 kA (9 MW). Pulse repetition loading is also demonstrated to mimic integration into a rep-rate pulsed power supply. Commentary on scalability of testing will be provided.
