High-Power 800V 400A Pulsed Constant-Current Power Supply Engineering
Pain Points (Public)
Scientific laboratories and advanced hardware teams need custom pulsed constant-current power supplies operating under extreme transient stresses (e.g., 800 V / 400 A pulse regimes), but struggle with severe voltage ringing from high dI/dt parasitic loop inductances, gate-drive timing skews across parallel switching modules, and strict thermal dissipation limits during repetitive burst discharges.
Suggested Approach (Public)
Deliver an end-to-end solid-state pulsed power supply architecture using fast SiC MOSFET or IGBT power stages. Model switching transients and loop parasitics in PLECS/LTspice, engineer a low-stray-inductance laminated busbar and multi-layer PCB layout in Altium Designer, implement galvanically isolated ultrafast gate drivers with active desaturation clamp protection, and configure high-bandwidth closed-loop current sensing for sub-microsecond pulse fidelity.
