Transformer power rating is greater than the desired supply output.

Volt-time product rating to be greater than the expected volt-seconds applied to transformer primary.

Online schematic capture lets hobbyists easily share and discuss their designs, while online circuit simulation allows for quick design iteration and accelerated learning about electronics.

Turns ratio must be selected to achieve desired output voltage. These tools allow students, hobbyists, and professional engineers to design and analyze analog and digital systems before ever building a prototype.

The output voltage should be an AC square voltage, but in the simulation it is basically a zero with spikes. There are three main considerations for selecting a transformer. I am trying to simulate very simple circuit: a transformer push-pull type. Typical Push-Pull Schematics for Texas Instruments SN6507

Combined with SN6507 transformer drivers from Texas Instruments, TX1 transformers offer a low EMI solution, with capability to operate over a much wider voltage range and offer higher power density.Ĭoilcraft’s current lineup of TX1 Series Transformers for Texas Instruments SN6507 is show below. While push-pull architecture has been in use for a long time and these benefits are well documented, Coilcraft TX1 Series transformers represent an advancement in transformer optimization for high frequency 1 MHz switching. In any case, push-pull switching power supplies offer simplicity of design, small transformer size, and excellent power density. Therefore, even without output regulation the output voltage is inherently well regulated if Vin is from a tight-tolerance voltage source. In a non-regulated push-pull supply, V OUT depends only on Vin and the transformer turn ratio. With push-pull supplies being forward-mode converters, V OUT in an output-regulated supply depends on the transformer turns ratio and the regulation scheme. Low peak current means small transformer size, low conduction loss and inherently low EMI.

Using push-pull switching drives the transformer primary in alternating directions and therefore utilizes the core very efficiently and reduces peak magnetizing current with less inductance than unipolar excitation. Push pull converter is like a buck converter but it has two drive winding isolation transformer.I will explain it later how to make high frequency transformer. Push-pull isolated switching power supplies are able to utilize the smallest possible transformers.
