What is the difference between a high-frequency switching power supply and a thyristor rectifier? (Take 18V8000A as an example)

1. Efficiency:
   Thyristor rectifier: about 70%;
   High-frequency switching power supply: 90%;
2. Transformer:
   Thyristor rectifier: composed of a power frequency transformer, very large in size, weighing 200kg;
   High-frequency switching power supply: no power frequency transformer, high-frequency transformer, weighing 30kg;
3. Adjustment device:
   Thyristor rectifier: thyristor;
   High-frequency switching power supply: IGBT;
4. Energy saving efficiency:
   Thyristor rectifier: poor;
   High-frequency switching power supply: obvious power saving, compared with ordinary thyristors, it can save 15% to 30% of power;
5. Control circuit:
   Thyristor rectifier: complex, with synchronization requirements, not easy to integrate;
   High-frequency switching power supply: easy-to-use special printed circuit board, fully anti-corrosion treated, completely sealed.
