In order to achieve a highly reliable and modular kicker system for the FCC injection, a semiconductor-based inductive adder (IA) pulse generator is being developed. To achieve the required high voltage and current, the IA consists of series-connected 1:1 pulse transformers (layers). The appropriate number of secondary windings are connected in series to generate the required voltage at the output. Each primary winding has many parallel primary branches to provide the high total current: each primary is referenced to ground. The modular design of many layers and parallel branches facilitates a fault tolerant design, which is important to reach the required high reliability. A fast rise time of 75 ns for the output current pulse (0.5 to 99.5 %), is a demanding performance specification. A prototype FCC IA has been designed and is presently under construction at CERN to investigae the technological limits. A first 10-layer prototype is currently being assembled: a 22-layer prototype will subsequently be built to provide the full 2.5 kA and 15.7 kV output pulses. This presentation gives an overview of the design parameters and the status of the prototype construction, together with the expected performance.
