【Abstract】 The over-current Protection circuit is an important part of the transistor series type direct current regulation source. With the purpose of high sensitivity and reliability, the design of the protection circuit can provide safe and reliable protection for the adjustment transistor which can be bearable to any voltage. It makes the series type regulating circuit’s output voltage increase greatly. In end of the paper, the writer gives an example:the trigger of cut-off type protection circuit and the design of the transistor series type direct current regulation source (output:100mA,0-750V )prove the protection circuit is practical.更多还原
