[0055] Contraction below Figure 5 ~ 6 The present invention will be further described in further detail.
[0056] The present invention proposes a high gain positive antitock layer boost converter, a circuit diagram of a converter such as Figure 5 Indicated. The number of turns of the primary winding of the transformer is n 1 , The number of turns of the secondary winding is n 2 , The number of turns of the third winding is n 3 K 1 K 2 For the ratio of transformers, where K 1 = N 2 / N 1 K 2 = N 3 / N 1 . D is the duty cycle of the power switch tube S, the control signal and the main waveform such as Figure 6 Indicated. The converter described in this application has a continuous and high efficiency characteristics in high gain conditions.
[0057] High gain positive anti-stacked layer boost converters use stacks and leak energy ideas. The third windings and diodes are introduced using laminated ideas. To reduce the volume of the converter, the third winding is coupled to the tran...
