【正文】 wn as aagainst the disciplinary action your employer has taken against you. However, if you win your case, the tribunal may reduce any pensation awarded to you as a result of your failure to appeal.Remember that in most cases you must make an application to an employment tribunal within three months of the date when the event you are plaining about happened. If your application is received after this time limit, the tribunal will not usually accept it.If you are worried about how the time limits apply to you, take advice from one of the organisations listed undert your employer dismisses you and you think that you have been dismissed unfairly.For more information about dismissal and unfair dismissal, see you don39。設(shè)計(jì)必須按期完成。第1天，選擇設(shè)計(jì)題目，確定設(shè)計(jì)任務(wù)，查閱資料；第2天，主電路設(shè)計(jì)；第3天，控制電路設(shè)計(jì)；第4天，仿真驗(yàn)證；第5天，完成設(shè)計(jì)。 （2）負(fù)載不變?yōu)?00，頻率1KHz，占空比從5%到95%以等百分比遞增時(shí)，直流升壓斬波電路的負(fù)載輸出波形及輸出電壓大小。19參考文獻(xiàn)[1] 王兆安，劉進(jìn)軍. 電力電子技術(shù)[M]. 5版. 北京：機(jī)械工業(yè)出版社,2009.[2] 張毅剛. 單片機(jī)原理及應(yīng)用[M]. 2版. 北京：高等教育出版社,2012.[3] 周永金. 模擬電子技術(shù)與應(yīng)用[J]. 西安：陜西國(guó)防學(xué)院電子教研室,2005.[4] 邊春遠(yuǎn),王志強(qiáng).
