Title: Switching power supply
Inventor: HAYASAKA JUNICHI
IPC: H02M3/28
Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To avoid unstable operation even when the switching frequency is synchronized with a horizontal deflection frequency by adding a rectangular signal for controlling the gate voltage, while integrating, to a current feedback signal. SOLUTION: A pulse width modulation circuit 16 outputs a rectangular signal for turning a switching element 5 on/off.
