Capacitors
Low Repetition Rate Bipolar Discharge Capacitors
These capacitors are optimized for normalized lightning waves generation, presenting very high peak currents and energy integrals. The voltage polarity can moreoover be inverted after each successive charge/discharge cycle.
Their outstanding self-healing properties guarantee high reliability performance.
Applications :
- Very fast energy restitution
- Generation of normalized lightning waves (8/20µs, 1,2/50µs, etc...)
- Lithotripsy
- Possibility of polarity inversion between successive discharges
