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.

关键词： digital control isolated power supply multi-resolution feedback method data transmission protocol

The purpose of this study is to investigate the biomass gasification system for power supply to introduce in rural communities of developing *** study was conducted using biomass gasification system(20 kW)which developed at Ashikaga *** general,for small scale power supply system using biomass gasification,reciprocate type engine or modified diesel engine are attached for power ***,biomass gasifier produces tar and it causes problems on smooth movement of piston in the reciprocate *** avoid effect by tar,the system is comprised the rotary engine coupled to a generator since there is no piston inside the *** for gasification system,downdraft gasifier is designed and *** this study woody biomass was *** gasifier performance was evaluated with respect to fuel consumption *** rotary engine-generator system was evaluated in terms of power generation *** of this study shows that fuel consumption rate was about 30 kg/h,gasification efficiency was about 63.4%and efficiency of rotary engine system was about 9.4%.

关键词： Biomass gasification isolated power supply rotary engine
