An effective data transmission protocol for multiple isolated power supplies based on multi-resolution feedback method

The paper proposes an efficient data transmission protocol for multiple isolated power supplies based on multi-resolution feedback method (MRFM). Adopting the nonlinear sampling method and the digital control technology, the MRFM can reduce the data bits of controlled variables without affecting the control accuracy and dynamic response, and can greatly improve the data transmission rate. In this paper, the effective data transmission protocol is well designed to overcome the magnetic saturation problem of the pulse transformer, and also easy to implement and realize. Simulation results verify the effectiveness of the MRFM.
