Case Study: Architecting a 500W 3-Phase Inverter Board
Designing a medium-power 3-phase inverter involves much more than simply stringing together six MOSFETs. When pushing 500W of continuous power, parasitic inductance, thermal dissipation, and gate drive isolation become critical engineering challenges.
Generating PWM with STM32
This day and age operate on minuscule chunks of extremely engineered silicon: microcontrollers. They govern almost everything electrical around us, utilizing control techniques for purposes as simple as temperature sensing, digital noise cancellation, or the...
Power Dissipation in Electronics: From Calculation to PCB
Understanding where power goes — and how to stop it from becoming a failure mode.
Capacitor as Pressure Sensor: Exploiting Deformation Physics
A parallel-plate capacitor under mechanical load becomes a surprisingly accurate force transducer — here's the physics and a practical circuit.
