Similarities: Both operate on the principle: Rectification → Inversion.
Unique Features: 400Hz Medium Frequency Power Supply: After rectification and inversion, it produces a pure 400Hz sine wave AC power supply for ground testing and aging of aircraft, radar, and other equipment. Medium Frequency Power Supply: After rectification and inversion, it produces an AC power supply with adjustable frequency from 400Hz to 10kHz, used for metal melting, heat preservation, sintering, welding, quenching, tempering, heat penetration, metal liquid purification, heat treatment, bending pipes, and crystal growth, etc. Aviation Ground Power Supply 2, 36V Aviation Power Supply 1, 400Hz Frequency Converter Power Supply 7, 115/200V Power Supply 2, 27V DC Power Supply 5, 400Hz Power Supply 12, Aviation Power Supply
