Abstract :
A 10kJ electromagnetic forming (EMF) modulator with energy recovery based on two resonant power modules, each containing a 4.5kV/30kA SCR, a 1.11 mF capacitor bank and an energy recovery circuit, working in parallel to allow a maximum actuator discharge current amplitude and rate of 50kA and 2kA/μs was successfully developed and tested. It can be plugged in standard single phase 230V/16A mains socket and the circuit is able to recover up to 32% of its initial energy, reducing the charging time of conventional EMF systems by up to 68%.
