There are two basic types of DC transformers, namely, a DC-DC converter whose output voltage is regulated and a “DC transformer” whose output voltage is adjusted with the input.

The basic requirements:
(1) Realize the electrical isolation of input and output voltage and the proportional relationship between input and output, and can realize multiple output;
(2) Use transformer leakage inductance for energy transmission, no energy consumption, conversion efficiency of 1, and high power density;
(3) The output does not need filter inductance, which can greatly reduce the volume and weight of the output filter, with good dynamic performance and fast transient response;
(4) The system frequency bandwidth can transmit voltage without distortion;
(5) Open loop control is adopted, the control circuit is simple, it is easy to realize soft switching, and the switching frequency can be further improved;
(6) High reliability, small electromagnetic interference to power supply and electrical equipment.
