What is the difference between high frequency switching power supply and 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 power frequency transformer, very large volume, weight of 200kg; High frequency switching power supply: no power frequency transformer, high frequency transformer, weight 30kg;
3.  Adjusting device: thyristor rectifier: silicon controlled; High frequency switching power supply: IGBT;
4. Energy saving efficiency: thyristor rectifier: poor; High frequency switching power supply: power saving is obvious, compared with ordinary thyristor, power saving 15% to 30%
5. Load start and stop: thyristor rectifier: unauthorized; High frequency switching power supply: Authorization;
6. Control circuit: Thyristor rectifier: complex, with synchronous requirements, not easy to integrate; High frequency switching power supply: easy to use, special printed circuit board, fully anticorrosive treatment, completely sealed.
