SIRIO脈沖驅(qū)動(dòng)變壓器TI系列介紹
根據(jù)與每個(gè)不同應(yīng)用領(lǐng)域相關(guān)的安全標(biāo)準(zhǔn)，當(dāng)需要將電脈沖從控制傳遞到功率級(jí)時(shí)，脈沖變壓器用于高頻功率轉(zhuǎn)換器，保持電路之間的電流隔離。
電信號(hào)施加到初級(jí)側(cè)并傳輸?shù)酱渭?jí)側(cè)，以發(fā)射功率BJT，功率MOSFET，IGBT，SCR，GTO，TRIAC。
特征
在高頻功率轉(zhuǎn)換系統(tǒng)中，由于設(shè)備參數(shù)的不同，如額定功率、額定電壓和電流、應(yīng)用領(lǐng)域等，有幾種不同的控制技術(shù)可供選擇。
脈沖變壓器的主要特點(diǎn)如下：
? n 初級(jí)到次級(jí)匝數(shù)比
? Vt 最小電壓*時(shí)間區(qū)域（稱為傳輸區(qū)域），可以在次級(jí)側(cè)使用單極性脈沖傳輸，而不會(huì)導(dǎo)致磁芯飽和，參考溫度為25°C
? LP 初級(jí)繞組電感
? Ck 繞組之間的耦合能力
? Ls 主泄漏電感，是在主側(cè)測(cè)得的電感值，二次繞組短路
? RP 初級(jí)繞組電阻
? RS 二次繞組電阻
? tr 上升時(shí)間，是在次級(jí)側(cè)連接額定負(fù)載電阻時(shí)傳遞脈沖所需的時(shí)間;該值與漏感值緊密相關(guān)
? Imax 最大二次電流，上升時(shí)間等于tr（額定負(fù)載電阻連接到次級(jí)繞組）
? Ip 額定初級(jí)有效電流（熱電流）
? fn 額定工作頻率（或最佳頻率范圍）
? Uis 兩個(gè)繞組之間的最大工作電壓
? Up 兩個(gè)繞組之間的隔離電壓
Pulse transformers are used in high frequency power converters, when it is required to trasfer an electrical pulse from the control to the power stage, keeping the galvanic isolation between the circuits, according to the safety standards related to each different application fields.
The electrical signal is applied to the primary side and transferred to the secondary side, to fire power BJTs, power MOSFETs, IGBTs, SCRs, GTOs, TRIACs.
Features
In high frequency power conversion systems, several control techniques are available and they differ from each other because of the striking apparatus parameters, like rated power, rated voltages and currents, field of application.
? n primary to secondary turns ratio
? Vt minimum voltage*time area (called transfer area) that can be trasferred at the secondary side with unipolar pulse, without causing the core saturation, referred to the temperature of 25°C
? LP primary winding inductance
? Ck coupling capacity between windings
? Ls primary leakage inductance, it is the inductance value measured at the primary side, with the secondary winding short-circuited
? RP primary winding resistance
? RS secondary winding resistance
? tr rise time, it is the time that takes to trasfer the pulse when the rated load resistance is connected at the secondary side; this value is tightly connected to the leakage inductance value
? Imax maximum secondary current, available with a rise time equal to tr (rated load resistance connected to the secondary winding)
? Ip rated primary effective current (thermal current)
? fn rated working frequency (or optimum frequency range)
? Uis maximum working voltage between two windings
? Up isolation voltage between two windings
