摘要： PROBLEM TO BE SOLVED: To provide a ripple voltage suppression device and a power conversion device that reduce power loss and are compact.SOLUTION: A voltage divider 3 detects a bus voltage V1 which is a DC output voltage of a rectifier 2 and divides it to a detected voltage V2 having a 1/N amplitude, a filter 4 extracts an AC component V3 in the detected voltage V2, and a voltage amplifier 5 amplifies it N times for application to an auxiliary winding 6b of a transformer 6 to generate a compensation voltage V5 across a main winding 6a having the same number of turns as the auxiliary winding 6b. A voltage of the same size as the AC component in the bus voltage V1 is thus generated across the main winding 6a as the compensation voltage V5 to cancel a ripple voltage in the DC output voltage of the rectifier 2, so that a DC voltage substantially free of ripple voltage is applied to a capacitor 7 and a resistance 8. The voltage amplification of the detected bus voltage V1 in the voltage amplifier 5 can dispense with DC current detection to implement power loss reduction and miniaturization.

摘要： PROBLEM TO BE SOLVED: To provide a gate drive circuit for a semiconductor switching element, capable of suppressing generation of abnormal voltage between main terminals at turn-off, by a simple configuration.SOLUTION: The same voltage as a voltage Vcc is inputted to a signal input terminal 7 as an off signal, and a voltage between the signal input terminal 7 and a terminal 6 becomes zero. A MOSFET 2 is turned off, and a MOSFET 3 is turned on. Electric charge stored in a gate is discharged as a gate current J1, and a semiconductor switching element 1 is opened. A voltage at the opening is detected by resistors 31 and 32 for voltage division. When the voltage becomes larger than a reference value, a voltage at a connection point 10 is forcibly reduced by an operational amplifier 5, and an injection current J2 is injected to a connection point 11 by an operational amplifier 4 so as to equalize the respective both-end voltages of a resistor 38 and a resistor 37 to suppress the gate current J1, and thereby, turn-off speed of the semiconductor switching element 1 is reduced to prevent generation of abnormal voltage. Since the gate current J1 is suppressed due to the injection of the injection current J2, a configuration for suppressing abnormal voltage can be simplified.
