RECTIFICATION DEVICE, ALTERNATOR, AND POWER CONVERSION DEVICE
摘要：
A rectifier including an autonomous type synchronous-rectification MOSFET is provided, which prevents chattering and through-current caused by a malfunction when a noise is applied. The rectifier (132) includes: a rectification MOSFET (101) for performing synchronous rectification; a determination circuit (103) configured to input a voltage between a pair of main terminals (TH, TL) of the rectification MOSFET (101), and to determine whether the rectification MOSFET (101) is in on or off state on the basis of the inputted voltage; and a gate drive circuit (105) configured such that a gate of the rectification MOSFET (101) is turned on and off by a comparison signal (Vcomp) from the determination circuit (103), and such that a time required to boost a gate voltage (Vgs) when the rectification MOSFET (101) is turned on is longer than a time required to lower the gate voltage (Vgs) when the rectification MOSFET (101) is turned off.
