Electronic circuit diagram showing a ZVS-QRAS Marx stage.

Here’s a comprehensive wiring guide for your 6-stage ZVS-QRAS Marx generator, including schematics, component placement, and critical layout details. This ensures optimal performance, safety, and efficiency. 1. Stage-by-Stage Wiring Diagram Each stage consists of 4x GaN FETs, 2x capacitors, 2x diodes, and LC snubbers. Below is the wiring for one stage (repeat Γ—6 for full Marx): Schematic ZVS-QRAS Marx Stage Wiring (Visual reference: Replace with actual schematic) Connections per Stage: Component Connection Points Notes GaN FETs (Q1-Q4) Q1/Q2: Source β†’ Ground, Drain β†’ Capacitor (+) Charging switches (parallel). Q3/Q4: Source β†’ Next stage, Drain β†’ Capacitor (-) Discharging switches (series, ZVS-enabled). Capacitors (C1/C2) C1: (+) β†’ Q1 Drain, (-) β†’ Q3 Drain Polypropylene film (0.2 Β΅F, 2 kV). C2: (+) β†’ Q2 Drain, (-) β†’ Q4 Drain Matched pair for balance. Diodes (D1/D2) D1: Anode β†’ C1 (-), Cathode β†’ C1 (+) QRAS energy recovery (SiC Schottky). D2: Anode β†’ C2 (-), Cathode β†’ C2 (+) Snubber (L1/C3) L1 (1 Β΅H): Q3 Drain β†’ Q3 Source Air-core inductor (min. parasitics). C3 (0.22 nF): Q3 Drain β†’ Q3 Source High-voltage ceramic (TDK). Gate Drivers LMG1210 OUT β†’ Q1-Q4 Gates Isolated drivers (1x per FET pair). 2. Inter-Stage Connections Charging Path (Parallel) Connect all Q1/Q2 Sources to a common ground plane. Link all Q1/Q2 Drains to the DC input bus (e.g., 1 kV) via a current-limiting resistor (10 Ξ©, 10W). Discharging Path (Series) Stage 1: Q3 Drain β†’ Output terminal. Stage 2-6: Q3 Drain See more
