Overlapping 50:50 push pull signals

Description

Generation of overlapping 50:50 push pull signals for a cascaded buck-push-pull-converter.

• Project Type: Free
• Complexity: Simple
• SPICE software: LTspice
• Software version: 4
• Full software version nedeed : No
• Description:

  Cascaded Buck-Push-Pull converters offer fast load regulation as well a sparing out some filter components, as the transformer acts as output inductor.

  This topology is a current fed one and therefore the current flow may not abort. Push-Pull signals need a short overlapping time.

  It took me some time figure out this easy way, after fiddling around with a SG3525 model and inverters...
