Publication number: 20170214313Abstract: A drive circuit for a semiconductor switching element includes an overcurrent protection circuit, a short-circuit protection circuit, and a determination time changing circuit. The overcurrent protection circuit judges that a principal current become an overcurrent when a sense voltage proportional to magnitude of the principal current excesses over a first threshold value, and then reduces the principal current. The short-circuit protection circuit reduces a gate voltage of the semiconductor switching element more quickly than the reduction of the principal current by the overcurrent protection circuit when the principal current becomes a greater overcurrent. The determination time changing circuit makes a determination time needed for determining whether or not to operate the overcurrent protection circuit longer when the magnitude of the principal current gets smaller based on a comparison result between the judgement result of the overcurrent protection circuit and a second threshold value.Type: ApplicationFiled: May 27, 2015Publication date: July 27, 2017Applicant: CALSONIC KANSEI CORPORATIONInventor: Yoshiyuki KIKUCHI
