Abstract:
(EN) An error amplification apparatus and a drive circuit comprising the error amplification apparatus. In the error amplification apparatus, a pulse generation circuit generates a first pulse and a second pulse according to an output voltage of an error amplifier unit, and a counting unit is connected to the pulse generation circuit and used for counting the first pulse and the second pulse, and generating a loop control signal reflecting magnitude of a compensation voltage based on the count. In the apparatus, the counting unit is used for digitizing a compensation voltage, the size of the count can reflect the magnitude of the compensation voltage, and accordingly, a loop control signal can be slightly changed within an AC period of 50Hz/60Hz to achieve a function of filtering out 50Hz/60Hz AC ripples. The apparatus reduces the size of a compensation capacitor, and therefore, the loop compensation capacitor can be integrated into an IC, thereby simplifying the peripheral design, and eliminating the impact on a loop caused by electric leakage due to humidity.
(FR) La présente invention porte sur un appareil d'amplification d'erreur et sur un circuit de commande comprenant l'appareil d'amplification d'erreur. Dans l'appareil d'amplification d'erreur, un circuit de génération d'impulsions génère une première impulsion et une seconde impulsion en fonction d'une tension de sortie d'une unité d'amplificateur d'erreur et une unité de comptage est raccordée au circuit de génération d'impulsions et utilisée pour compter la première impulsion et la seconde impulsion, et générer un signal de commande de boucle reflétant l'importance d'une tension de compensation sur la base du comptage. Dans l'appareil, l'unité de comptage est utilisée pour numériser une tension de compensation, la taille du décompte peut refléter l'importance de la tension de compensation et, par conséquent, un signal de commande de boucle peut être légèrement modifié pendant une période de courant alternatif (CA) de 50 Hz/60 Hz pour obtenir une fonction de filtrage des ondulations de courant alternatif de 50/60 Hz. L'appareil réduit la taille d'un condensateur de compensation et, par conséquent, le condensateur de compensation de boucle peut être intégré dans un circuit intégré (CI), ce qui permet de simplifier la conception périphérique et d'éliminer l'influence sur une boucle provoquée par une fuite électrique due à l'humidité.
(ZH) 一种误差放大装置和包含所述误差放大装置的驱动电路,该误差放大器装置中,脉冲发生电路根据误差放大器单元的输出电压产生第一脉冲和第二脉冲,计数单元连接所述脉冲发生电路,对第一脉冲和第二脉冲进行计数,并基于所述计数生成反映补偿电压大小的环路控制信号。该装置使用计数单元把补偿电压数字化,计数值大小可以反映补偿电压的高低,据此可以使得在交流50Hz/60Hz的周期内环路控制信号的变动很小,达到滤除50Hz/60Hz交流纹波的作用。上述装置减小了补偿电容的大小,由此可将环路补偿电容集成到IC内部,简化了外围设计,消除潮湿漏电对环路的影响。
