Voltage reduction through transformer → rectification and filtering into DC → regulator stabilization. Small adjustable current range, low output ripple (suitable for precision equipment).
Convert DC to high-frequency AC → quickly switch through switching tubes → step down with transformers → rectify and filter into DC. High efficiency but slightly higher ripple (suitable for high current scenarios).
Example: Choose a linear power supply (with stable voltage) to power a microscope, and choose a switching power supply (light, small, and high efficiency) to charge a phone.
Linear Power Supply: Large volume and weight (over 1kg) due to the need for a large transformer and rectifier filter circuit.
Switching Power Supply: High-frequency circuit and integrated design yields small size (only 1/3 of linear types) and light weight (within 500g). Preferred for portable devices like drones and laptop chargers.
Linear Power Supply: Energy conversion relies on resistance heating, resulting in about 60% efficiency (e.g., input 100W, output 60W).
Switching Power Supply: High conversion efficiency (80%-95%), generating almost no heat (e.g., input 100W, output 90W+), saving energy costs over time.
Linear Power Supply: Features extremely low output ripple (<10mV), making it excellent for sensitive equipment like medical instruments and laboratory hardware.
Switching Power Supply: High-frequency switching may introduce some ripple (>20mV), though modern filtered designs make it suitable for most standard devices.
Linear Power Supply: Fast transient response (microsecond level) as the regulator directly responds to voltage changes, fitting precision dynamic experiments.
Switching Power Supply: Slightly slower transient response (millisecond level) due to switching delay, though negligible for most devices.
| Scenario Requirements | Preferred Choice | Core Reasons |
|---|---|---|
| Portable devices (mobile phones, laptops) | Switching power supply | Small size, high efficiency, wide voltage input |
| High power equipment (servers, motors) | Switching power supply | High efficiency, low cost, no heat dissipation pressure |
| Precision instruments (oscilloscope, mass spectrometer) | Linear power supply | Low ripple, low noise, stable voltage |
| Low power fixed scenario (router, microcontroller) | Linear power supply | Low cost, high reliability, simple circuit |
| Audio equipment (amplifier, DAC) | Linear power supply | No switch noise, avoiding interference with sound quality |
