【摘要】:隨著科技的發(fā)展和車輛的普及,人們逐漸將汽車視為一種可代步亦可娛樂(lè)的交通工具。越來(lái)越多的車主會(huì)在自己的車輛上裝載電子設(shè)備,如:可移動(dòng)電視、音響、DVD等等,且越來(lái)越多的人會(huì)在車輛上使用手機(jī)、平板等可移動(dòng)電子設(shè)備。因此,車載逆變電源被越來(lái)越多的人需要。 為了適應(yīng)車載電子設(shè)備的需求,逆變電源的設(shè)計(jì)要求是從12V直流電源升壓逆變到220V/50Hz交流輸出。 本文采用高頻升壓及正弦波逆變的方式設(shè)計(jì)了一款從12V升壓逆變到220V交流電的車載逆變器。高頻升壓采用推挽式電路拓?fù)浣Y(jié)構(gòu),控制模式采用電流型PWM控制模型。相比于其他電路拓?fù)浣Y(jié)構(gòu),推挽式具有變壓器體積小、利用率高,輸出電流紋波小的特點(diǎn)。電流型PWM控制策略,相比于電壓型PWM模式,前者能有效防止因磁芯偏磁帶來(lái)的災(zāi)難性的影響,使電路安全工作。本文在升壓設(shè)計(jì)中利用了Saber仿真軟件進(jìn)行輔助設(shè)計(jì)。Saber仿真能夠較為準(zhǔn)確分析電路中存在的漏感,對(duì)變壓器參數(shù)的設(shè)計(jì)以及吸收回路的設(shè)計(jì)有很大的幫助。正弦波逆變器采用全橋逆變電路拓?fù)浼癝PWM控制策略,其中利用光耦電路作全橋開(kāi)關(guān)管的驅(qū)動(dòng),自然采樣原理作為SPWM的控制方法。經(jīng)濾波后可使輸出接近正弦波。 本文實(shí)現(xiàn)了輸入9~15V直流,輸出220V/50Hz交流電的設(shè)計(jì),輸出功率最高可達(dá)150W。
[Abstract]:With the development of science and technology and the popularization of vehicles, people gradually regard the automobile as a kind of transport which can be used for transportation and entertainment. More and more owners will load electronic devices on their vehicles, such as mobile TV, audio DVD and so on, and more people will use mobile phones, tablets and other mobile electronic devices in their vehicles. Therefore, the on-board inverter power supply is more and more people need. In order to meet the demand of onboard electronic equipment, the design requirement of inverter power supply is from 12V DC power source boost inverter to 220 V / 50 Hz AC output. In this paper, an on-board inverter from 12V boost inverter to 220V AC inverter is designed by means of high frequency boost voltage and sine wave inverter. The push-pull circuit topology is used in the high frequency boost, and the current PWM control model is used in the control mode. Compared with other circuit topologies, push-pull type has the characteristics of small volume, high utilization ratio and small output current ripple. Compared with the voltage-mode PWM control strategy, the former can effectively prevent the catastrophic effect caused by magnetic core bias tape and make the circuit work safely. In this paper, the saber simulation software is used to analyze the leakage inductance in the circuit, which is helpful to the design of transformer parameters and the design of absorption circuit. The sinusoidal inverter adopts the full-bridge inverter topology and SPWM control strategy, in which the optocoupler is used as the drive of the full-bridge switch, and the principle of natural sampling is used as the control method of SPWM. After filtering, the output can be close to sine wave. In this paper, the design of input 9V 15V DC and output 220V / 50Hz AC is realized. The output power can be up to 150W.
