Characteristics Analysis of High Power Marine Electromagnetic Transmitter DC-DC Controlled Source Circuit
摘要
Abstract
Marine electromagnetic transmitter transmits large power electromagnetic wave to the seabed for obtaining the submarine structure and mineral resources. However, the current transmitter has the problems of large volume and low transmission power. In this paper, PWM converter is used to construct the DC-DC controllable source circuit. Since the conventional zero voltage switching full bridge (ZVS-FB) PWM converter has many limitations, such as high loop energy, loss of duty cycle and limited ZVS range of lagging bridge arm, a zero voltage zero current switching full bridge (ZVZCS-FB) controlled source circuit is proposed using asymmetric phase-shifted control. The operating process and circuit characteristics of ZVZCS-FB-PWM DC-DC controlled source circuit are analyzed, including the maximum control duty ratio, reset primary current and capacitance, the loss of the duty ratio, the switching loss and energy circulation etc. Simulation and experimental results show that the DC-DC controlled source circuit realizes the leading-leg switches to be operated with ZCS turn-on and ZVS turn-off, the lagging-leg switches with ZCS turn-on and turn off. The circuit efficiency and power density are accordingly improved.关键词
