Abstract

The invention discloses a ripple peak suppression type low loss portable switch power supply. The switch power supply is characterized in that the switch power supply is composed of a control chip U2, a transformer T1, a transformer T2, a diode rectifier U1, a fly-back converting circuit, a ripple peak suppression circuit which is in series connection to a cathode output end of the diode rectifier U1 and a VC base pin anode of the control chip U2, and a high impedance voltage following circuit which is in separate connection to a dotted terminal and a non-dotted terminal of a secondary side inductance coil of the transformer T2. According to the invention, the switch power supply can effectively reduce current conductance loss and current loss caused by the circuit, and the switch power supply can also regulate pulse width, and effectively avoid the intensity of the magnetism of a magnetic assembly, so that effective reduction of current loss can be guaranteed and the stability of output current can be effectively increased.

Description

technical field [0001] The invention relates to the field of aluminum electrolysis, in particular to a ripple peak suppression type low-loss portable switching power supply. Background technique [0002] The rise and development of portable switching power supply has injected fresh blood into the modern electronics industry, and after a long period of development, portable switching power supply has become an indispensable part of electronic products used in people's lives. Therefore, whether the performance of portable switching power supply Stability has become an important factor in whether the working state of electronic products is stable.
