Speed Enhancement Technology for Capacitive Charging High Voltage Power Supplies

I. Technical Background and Core Challenges 
Capacitive charging high-voltage power supplies require charging rates to leap from conventional 10kV/ms to 100kV/ms levels, facing three bottlenecks: 
1. Dielectric polarization hysteresis (>5ns) under high power density 
2. Dynamic losses from switching devices (30% energy loss at >10kHz) 
3. Parasitic parameter coupling causing resonant effects 

II. Speed Enhancement Approaches 
1. Topology Innovation 
   Hybrid Marx-LLC topology achieves 92% efficiency at 80kV/10nF charging 
   3D laminated busbars reduce loop inductance to 7nH 

2. Wide Bandgap Semiconductor Technology 
   SiC MOSFET modules reduce switching losses by 65% 
   Integrated packaging lowers thermal resistance to 0.25℃/W 

3. Hybrid Energy Storage 
   HESS systems reach 50kW/kg power density 
   Multiphase charging reduces balance error to <0.5% 

4. Intelligent Control 
   MPC algorithm limits voltage tracking error to ±0.3% 
   Digital twin systems achieve 0.8μs speed stability 

III. Application Cases 
1. Laser Processing 
   200kW laser power supply charging time reduced to 80μs 
   ±2μm cutting accuracy achieved 

2. Medical Imaging 
   CT generator repetition rate reaches 2kHz 
   0.1mAs dose control precision realized 

3. Energy Research
