Advantages of a Capacitor

• High efficiency
• Maximization of space and energy efficiency
• Low internal resistance
• No mechanical energy loss due to moving parts

CVM-60 Timing Circuit

• Will allow us to regulate the discharge of the
  capacitors by allowing us to release the current
  in pulses
• Input/Output voltage also adjustable
• (See Chart to right)
• Maximum efficiency when input voltage equals
  output voltage
• Exact pulse speed to be determined by generator
