in compare with Switching Power Supply

- minimum four time smaller
- minimum twice cheaper
- more effective - over 90% (any load)
- less non load consumption - about 1W
- minimum RF emission -9kHz (second harmonic18kHz)

This technology have reserve and build to silicon chip can be frequency and power five time bigger in the same size and non load consumption can be next ten time smaller. This is realy revolution in Power Supply Technology.

Pulse Power Supply can save 20% of consumption world home electric energy.

SCHEMATIC - half bridge topology

With planar ferrite core PQ2610 can be designed - universal input 110/220V - 50W/100W or the same size 110V/100W with bigger capacitors on smaller voltage. Output power and effective depend on quality of PCB coil (more layer and high Cu plated = less lost) and quality choke and current and rectifier on secondary part.

100W (45x35x25mm) Pulse Power Supply (planar ferrite core PQ2610)

50W (35x25x20mm) Pulse Power Supply (planar PQ2010)

V2.0

compare size 50W and 100W Pulse Power Supply and 50W Switching Power Supply

osciloscope output - green is output with 10Ohm rezistor (100W - PQ2610, 0.3mm 26primary, 0.5mm 2x5 secondary wire, one 10uH choke and 1G/50V on output, 2x 0.1uF and 33uF/400) - without regulation (max power) without filtering (min 96W max 115W)

Planar ferrite core PQ2610 can be use to 120W and PQ2010 to 50W on 9kHz frekvency.

Planar ferrite core is from ...........COSMO FERRITES LIMITED
Power supply operate on voice frequency therefore ferrite must be glued

DC/DC 50W Pulse Power Supply (lo voltage hi current module PULSE)
non isolation power supply, for small power coil is not necassary, wide voltage input 15-600V
with standard modul PULSE is input 90-350V
(DC/DC not tested, so is very simple)
