  • Controlling Brushed DC Motors Using PWM - Optimal Frequency, Current Ripple, and Life Considerations
    regulation power supplies or through Pulse Width Modulation (PWM). The linear regulation is generally inefficient and demands increased housing space. Moreover, in battery-driven applications, it becomes impractical to use the linear regulation at varying load points. PWM voltage regulation, on the other

  • Glass vs. Metal CO2 Laser Tubes
    cooling system also presents some significant safety concerns. The DC power supplies that excite the CO2 gas in a glass laser tube need to operate at very high voltages. When you combine such levels of voltage with a water cooling system, the results can be lethal should something go wrong
  • Relays: Principle of Operation for Engineers
    High current switching technology. Ledex-BLP-200 In the drive towards smart metering and control for domestic power supplies, the solenoid-operated power contactor is a key enabling technology. Utility companies and equipment manufacturers are increasingly looking for added value in this type
