Title: Switching power supply
Inventor: NAGAHARA KIYOKAZU
IPC: H02M3/28
Filed: 2000-12-18
Abstract: PURPOSE: To protect switching elements when the power supply to a switching power unit is turned on. CONSTITUTION: The switching power unit comprises a switching signal generating means 12 having a variable oscillation circuit 14, switching elements 22 and 24 to which switching signals are supplied, and a capacitor 28 for resonance connected to the junction of the switching elements 22 and 24 through a primary coil 26a. The power unit also comprises the secondary-side rectifier circuit 42 of a transformer, a comparing means 36 which compares the output voltage Vb of the circuit 32 with a reference voltage Vref, and an impedance control means 37 which controls the impedance of the oscillation element of the oscillation circuit 14 based on the comparison output of the comparing means 36. In addition, the power unit also comprises a frequency control means 80 which controls the oscillation frequency of the oscillation circuit 14 at the initial driving time of the circuit 14. The frequency control signal outputted from the control means 80 when the power supply to the power unit is turned on is made to have a nonlinear characteristic with respect to time. Consequently, the change of the oscillation frequency of the circuit 14 immediately after the power supply is turned on becomes gentle and the abrupt change of the current flowing on the primary coil 26a side is eliminated. Therefore, the switching elements 22 and 24 can be protected surely, because no overcurrent flows to the elements 22 and 24 and the damages of the elements 22 and 24 can be reduced significantly from the conventional example.
