【摘要】：采用傳統(tǒng)晶閘管相控電源供電的電除塵器存在能耗高、效率低等問題,文章設(shè)計(jì)了一種可以解決這些問題的電除塵器用高壓脈沖電源,該電源主電路主要由移相全橋逆變電路和10組相對(duì)獨(dú)立的脈沖輸出單元構(gòu)成。采用移相全橋ZVT-PWM軟開關(guān)技術(shù)控制逆變電路前后橋臂的相位差;采用同步驅(qū)動(dòng)技術(shù)驅(qū)動(dòng)各脈沖輸出單元,使各輸出脈沖疊加后獲得高壓脈沖;DSP準(zhǔn)確控制電源輸出高壓脈沖的電壓、頻率和脈寬。結(jié)果表明高壓脈沖電源提高了電除塵器的除塵效率,減少了對(duì)電網(wǎng)的干擾和電能損耗,能滿足多種電除塵的要求。
[Abstract]:The electrostatic precipitator powered by traditional thyristor phase-controlled power supply has the problems of high energy consumption and low efficiency. This paper designs a high voltage pulse power supply for electrostatic precipitator which can solve these problems. The main circuit of this power supply is mainly composed of phase-shifted full-bridge inverter circuit and 10 groups of relatively independent pulse output units. The phase shift full-bridge ZVT-PWM soft switch technology is used to control the phase difference between the front and back arms of the inverter circuit, and the synchronous drive technology is used to drive the output units of each pulse, so that the voltage of the high-voltage pulse output can be accurately controlled by the high-voltage pulse ZVT-PWM after the superposition of each output pulse. Frequency and pulse width. The results show that the high voltage pulse power supply can improve the dust removal efficiency of the electrostatic precipitator, reduce the interference to the power grid and power loss, and can meet the requirements of a variety of electrostatic precipitators.
