❓ Frequently Asked Questions
What is power electronics?
The field that uses solid-state devices to convert and control electrical power, enabling voltage/current/frequency regulation with high efficiency.
What are the main power converter types and common topologies?
DC-DC converters (buck, boost, buck-boost) regulate DC voltage; AC-DC rectifiers convert AC to DC; DC-AC inverters convert DC to AC; PWM is often used to regulate the output.
What is PWM and why is it used?
Pulse-width modulation controls a switch’s on/off time to shape the average output voltage/current, improving regulation and efficiency while reducing harmonics.
What affects efficiency and where do losses come from?
Efficiency is the ratio of output to input power. Losses include switching losses, conduction losses, core/transformer losses, and gate-drive losses.
How do designers choose a converter topology?
They consider input/output ranges, required regulation, efficiency, size, cooling, and cost; buck for step-down, boost for step-up, and inverters for DC to AC.
