And finally, zero current switching-on is realized by the 3 freewheeling diodes, and the voltage stress of the output diode is fully reduced. It can be used in new energy system occasions.
Description
Technical Field
The invention relates to a coupled inductor hybrid lifting voltage converter. Belongs to a boosting direct current converter with high gain ratio.
Background
With the shortage of energy and the increasing severity of environmental pollution, the demand for renewable energy is becoming more and more prominent, and more people in the world expect the use and development of renewable energy in daily life. However, the conventional BOOST converter cannot have a high duty ratio due to the influence of parasitic parameters, so that the BOOST converter has a low voltage gain capability, a large voltage stress of a switching tube and a severe power loss, and therefore, the BOOST converter cannot provide a high enough voltage gain ratio to increase the voltage to meet the requirement of grid connection under the condition of high efficiency. For this reason, although cascade BOOST converters and the like have been developed, when a high BOOST ratio is realized, the number of devices generated by cascade is increased, the problem of low efficiency is prominent, and the circuit becomes complicated. The advent of coupled inductor technology has improved the ability of the converter to gain boost, but it is also critical that the efficiency of the converter be greatly reduced due to voltage spikes caused by leakage inductance. Therefore, the research on the novel high-gain converter is urgent to be a practical requirement and has important theoretical significance.
