Title: Forward type dc-dc converter
Inventor: MATSUMOTO YOSHIAKI
IPC: H02M1/12
Filed: 1996-11-15
Abstract: PROBLEM TO BE SOLVED: To increase a power factor and an efficiency and reduce noise by controlling the frequency so that a switching element may be turned on after detecting a zero point of inductance current which is the output of the converter when increasing the power factor without using an input capacitor. SOLUTION: The current of an inductance 9 which is the output of a converter is detected by a resistance 16 and then a zero point of the inductance current is detected by a comparator 17. Then, the signal of the comparator 17 is supplied to a pulse generator 13'. In the pulse generator 13', the frequency of the pulse is so controlled that the pulse may be turned from an off-state to an on-state when the inductance current becomes zero with the ON width being constant. The frequency-controlled pulse is so controlled by a minimum OFF width limiting circuit 18 that the OFF width may exist without fail in each cycle and then the pulse is supplied to a driving circuit 14. The driving circuit 14 applies the frequency-controlled driving pulse to a main switching element 4.
