Title: Switching power source device
Inventor: NAKAHIRA KOJI
IPC: H02M3/28
Filed: 1991-11-18
Abstract: PURPOSE:To correct fluctuation in an input voltage and to reduce an irregularity in an overcurrent protection starting point due to the fluctuation in the voltage by superposing a voltage obtained by dividing the input voltage by an overcurrent detecting resistor and a correcting resistor on a voltage across the resistor connected in series with a switching element. CONSTITUTION:A correcting resistor R2 20 is connected between a connector of a MOSFET 4 and a resistor R1 6 and the opposite side of a primary winding of a transformer 2 to the MOSFET 4. Here, when an input voltage V1 falls, a switching frequency is reduced, and a peak value of a drain current I1 is raised with respect to the same output current I2. Accordingly, a voltage V0 across the resistor R1 6 and a voltage across the resistor R2 20 cancel the variation in the voltage V1. Therefore, if the values of both the resistors R1 6 and R2 20 are suitably selected, the voltage V0 across the resistor R1 6 can be set to almost no variation with respect to the fluctuation in the voltage V1, and an irregularity in an overcurrent protection starting point due to the fluctuation in the voltage V1 can be reduced.
