Title:
POWER CIRCUIT
Document Type and Number:
Japanese Patent JPH07274500
Kind Code:
A
Abstract:
PURPOSE: To prevent the occurrence of noise by needless radiation by arranging a inductance in series to the diode, in a power circuit which forms a snubber circuit.
CONSTITUTION: An inductance 22 is arranged between a diode 9, which forms the snubber circuit of a power circuit 21, and the primary low-voltage terminal of a switching transformer 5. Hereby, needless radiation can be reduced by suppressing the sudden ripple of the current flowing to a snubber circuit, and repressing high frequency ingredients, and also the damage, etc., of a diode 9 can be avoided effectively by reducing the peak value of a surge current, too.
