An All-Solid-State Inductive Voltage Adder For Industrial Applications — •Werner Hartmann, Martin Hergt, and Robert Fleck — Siemens AG Corporate Technology, Erlangen, Germany

The development of an Inductive Voltage Adder (IVA) designated for industrial applications like electroporation, environmental applications, etc. is reported. The IVA concept has the feasibility of using conventional high power IGBT semiconductor switch modules instead of spark gaps or arrays of low-power IGBTs. It is designed to produce pulses with pulse durations of typically 1 us FWHM (full width at half maximum). A three-stage IVA demonstrator is tested in single pulse mode and at low repetition rates due to load and power supply constrictions. A maximum pulse repetition rate of around 2 kHz is estimated without additional forced cooling of the semiconductor switches. The technology of the IVA driven with semiconductor switches promises longer lifetime, higher pulse repetition rate and average power, higher reliability and lower maintenance requirements as compared to pulse generators utilizing spark gap switches. Experimental results are presented for which prove that the IVA concept is feasible as a scalable pulsed power generator for commercial applications at pulse durations of typically 1 us.
