Communication with the transformer, the non-linear distortion is a very important indicator, thus requiring the transformer in the initial permeability of the core, as well as the input transformer that even very small power transformers, shape had made considerable . In addition to considering the frequency characteristics of the transformer, how to reduce the problem of loss is a very concerned about. In contrast to this, in terms of the pulse transformer as the main consideration waveform delivery problems. Even if it is a wideband transformer, but as long as the waveform can meet the design requirements, the core can also work in a non-linear region. Thus, its shape can do better than to communicate with a lot of small transformers. Also, in addition to high-power pulses through, the transmission loss of the transformer is generally not large. Therefore, the size of the core taken depends on the pulse through the magnetic flux is saturated, or depending on whether the temperature rise caused by iron loss exceeds the allowable value. Today, the latest analysis of the pulse transformer, pulse transformer is handled by distributed constant type, called transmission type pulse transformer. It works pulse transformer works by magnetic saturation of the core properties of the input sine wave voltage into a narrow pulse shape of the output voltage transformer. Can be used for burner ignition, triggered thyristors and the like. Pulse transformer primary winding structure is set in a large section of the core quartet built silicon steel column, the secondary winding section set in the permalloy alloy material is less easy to highly saturated core column, two columns in the middle can be a magnetic shunt. Relationship between voltage and flux, the input voltage u1 is a sine wave, sinusoidal flux Φ1 iron hearts on the left. The right iron core flux Φ2 highly saturated, are flat-topped waves, it only changes occur in the vicinity of zero value, and immediately reaches the saturation value. When the moment Φ2 zero-value in the secondary winding on a very steep narrow induced electromotive force pulse e2. Magnetic shunt air gap exists, Φσ substantially varies linearly with the magnetic flux leakage is similar to its role is to ensure that Φ1 sine wave. All pulse transformer between the two basic principles of ordinary transformers (such as audio transformers, power transformers, power transformers, etc.), but on the magnetization process core that point of view is different, as follows: (1) pulse Transformer is a work in transient transformer, that is, the pulse process occurs in a short period of time, is a top smooth square wave, while an ordinary transformer is operated in a continuous change in the magnetization, the alternating Press sinusoidal signal is changed. (2) The pulse repetition period signal, spaced apart, and only positive or negative voltage, and the alternating signal is continuously repeated, both positive and also negative voltage. (3) pulse transformer transmission waveform distortion claim, which is required to the forefront of the waveform, the top down to be as small as possible, but these two indicators are contradictory, the main purpose pulse transformers are widely used in radar, changing technology; the load resistance matching the characteristic impedance of the feeder; increase or decrease the pulse voltage; changing the polarity of the pulse; application isolation transformer secondary circuit and the primary circuit of several secondary windings in order to obtain the phase relationship; isolated power supply part of the DC component; the transistor ( or tube) pulse oscillator manipulation collector (anode) electrode (gate) and a base to give a strong coupling between; the use of a number of secondary windings in order to get a few pulses of different magnitudes, so tubes plate loop and collector and the base gate circuit or transistor formed between positive feedback in order to generate self-oscillation; as the power synthesis and conversion components. Profile: Sichuan Hongli Electric Co., Ltd. was established in 2006, located in Chengdu, the company formerly known as Xi'an Power Electronics Technology Institute in southwest office, which was established in late 2000 in Chengdu, Sichuan, located in the Southwest Jiaotong University . With many senior experts and complete electrical technology R & D team, after the business development needs, the Xi'an Power Electronics Technology Institute and other leaders agreed to examine the the Southwest Office in March 2006 successfully registered as the "Sichuan Hongli Electric Co. Ltd. ", the company registered capital of 5.03 million yuan, the legal representative: cold their show. The company in recent years of rapid development, the company benefited from the establishment of the early establishment of a more scientific, more comprehensive enterprise standard system. After several years of development, the company has established in the market a higher profile, and Kawauchi many large state-owned, private enterprises to establish a long-term supply and demand relations of cooperation, won a good reputation of many customers.
