Go Green With PSpice

Learn how electrical designers can use PSpice to help move to a sustainable future.

What Issues Are Faced Today?

As electronic devices become increasingly universal, a major issue is the amount of e-waste generated and its impact on climate change. Component material selection, operating temperatures, and product longevity impact the life of electronic devices. But how does the management of junction temperature impact the device's lifetime, contributing directly to climate change and e-waste produced? A lot more than previously recognized.

Issues Due to High Junction Temperature

  • Increased leakage current
  • Faster degradation of Gate oxides – Reduced MTBF
  • Higher conduction loss – a faster movement of Ionic impurities
  • Higher Mechanical stresses
  • Increased MOSFET on-resistance
  • Reduced MOSFET threshold voltage
  • Slower bipolar transistor switching
  • Reduced Beta for a bipolar transistor
  • Chances of current hogging and thermal runaway
  • Increased breakdown voltages- Generally good
  • Reduced Safe Operating Areas (BJTs)

 

PSpice Smoke Analysis analyzes the circuit's operating conditions and manages steady-state operating temperatures. Increasing the device's lifetime while decreasing the rate at which used materials go into e-waste and new materials are mined reduces the amount of e-waste generated worldwide.

Why PSpice

The pandemic created a surge for electronic devices, driving the increased demand for digital devices and causing electrical engineers to face tighter time-to-market while still delivering best-in-class performance. Pair this with the effects of increased e-waste, and it’s a larger problem than just fulfilling demand.

PSpice Simulations Help Reduce the Device Failure Rate, Enabling You to:

  • Select components with minimal chemical footprint and verify with PSpice for the best results.  
  • Save time, money, and the environment with circuit simulation and verification to burn fewer to almost zero prototypes and reduce overall e-waste.
  • Design reliable products with longer product life to reduce raw material needs.
  • Test for extreme operating conditions from sub-zero temperatures to 50ºC +.
  • Design and Manage Derate Standards to increase device longevity due to running at optimal temperatures.
  • Increase yield optimization with Monte Carlo and maximize the resources available.

 

PSpice is Uniquely Suited to Help

  • Use PSpice simulations to design robust energy-efficient power adapters and battery chargers that optimize minimum power usage.
  • PSpice has strong power electronics simulation capabilities, making it a good fit for electronics design simulation for electric vehicles (EVs), solar, and wind power equipment.
  • PSpice-MATLAB co-simulations can co-simulate electrical-mechanical systems in EVs and wind turbines.

 

Be an environmental change leader by creating designs that optimize power, decrease raw material consumption, and reduce overall e-waste.
