Power Efficiency Showdown: Simulating Voltage Boosting Circuits
2025-04-28
This post compares the power efficiency of several voltage boosting circuits using the Lush Projects circuit simulator. Circuits tested include a buck converter, parallel buck converter, serial buck converter, pulsed transformer, and Joule thief. All circuits boosted a 5V DC input to a stable 10V output, measured across a 1kΩ resistor load. The parallel buck converter proved most efficient (92.73%), followed by the serial (91.32%) and standard buck converter (88.43%). The pulsed transformer was least efficient (73.85%), while the Joule thief lagged far behind at only 22%. The author discusses component choices (capacitors, resistors, MOSFETs) and their impact on efficiency.
