This paper reviews the state of development of aviation power and aviation static converter. Considering the urgent need of planes to aviation static converter of high voltage, large current and high power output, this paper mainly studied the DC/DC stage of high voltage dc aviation static converter, and designed the phase shifted ZVS PWM full-bridge converter with two clamping diodes as the basic topological cell of the first stage of the two-stage static converter. Meanwhile the paper analyzed the working principle of the phase shifted ZVS PWM full-bridge converter with two clamping diodes, and then a simulation was run by using the software Saber, which proved theoretical analysis right.

Applications of modern terminal loads and its relevant disadvantages are described in this paper. The decomposing method of wideband microwave high power microstrip loads design is proposed in this paper with purpose of matching quality improving. Multiple extension of multistage load bandwidth is provided by using of external matching circuit and internal matching inductive elements. The maximum reachable bandwidth of multistage load is estimated and optimal values of mathing circuit elements are founded on basis of equivalent lumped scheme. The topology of microstrip two-stage high power microwave load is developed and its frequency response, calculated via numeric electrodynamic modelling method is outlined in the paper. Modelling results show good matching quality of considered load at the frequency band below 3,5 GHz.
