A switching mode power supply generating reduced high frequency noise. The power supply includes a solid state switch, a modulator for driving the solid state switch with a periodic pulse drive signal, an output filter at the output of the solid state switch, where the output filter includes ...

Switching supplies may be used, though special care must be taken to ensure optimum performance, as noise on the power supply can affect the operation of the radio. Most step-up and step-down switching supplies, and even some RS232 level converters, can introduce ripple into the power supply...
PURPOSE:To obtain a noise-reducing device, to be used for a core, a choke coil and a switching power supply at low cost, in which a filter circuit can be made small in size at low cost by increasing the leakage inductance of a common mode choke coil L1. CONSTITUTION:In the choke coi...
can be simplified by unsoldering it with a "solder sucker" instead of removing it completely from the printed circuit board. I have seen very few failures of the +5 volt output diodes. All diodes must be replaced with high-speed diodes or the power supply will generate excessive noise. ...
