This would be less of a step-up than the custom wound option in TomGeorge's post, but I suppose driving it with a full H-bridge (12+/12-) would compensate for this in comparison to the driver circuit referenced in the TomGeorge post??? How would this transformer's inductance (400uH @ 10kHz) affect a driving circuit?

The right transformer selection means saving a lot of money. We got to know, the minimum input to our selected regulator IC is 7V (See above datasheet values). So, we need a transformer to step down the main AC to at least this value. But, between the regulator and secondary side of the transformer, there is a diode bridge rectifier too.
Jan 06, 2004 · The waveform of the full bridge was not as aspected. Below is the Vpulse setting that i set for my full bridge to operate : V1=0, v2=15 td= 1n tr=1n tf=1n pw=5u per= 10u (this setting same for all 4 switches) I check waveform at Vp( transformer primary) but i just manage to get it correctly. Can anyone advice me on this? Appreciate..
Abstract—This paper presents the design, modelling and control of a three-port (TPC) isolated dc-dc converter based on interleaved-boost-full-bridge with pulse-width-modulation and phase-shift control for hybrid renewable energy systems. In the proposed topology, the switches are driven by phase-shifted
This AC to DC calculator is for a circuit with a full wave bridge rectifier as shown above. If you had a transformer with known AC output voltage at the secondary, and you needed to know the DC voltage to expect after rectification, then this page will help.

Simple Control Method Tames Flux Saturation In High-Frequency Transformer-Link Full-Bridge DC-DC Converters Focus: The high-frequency transformer-link dc-dc converter is the preferred topology for low- and medium-power plasma-cutting applications since it is compact, light and provides good dynamic response along with galvanic isolation.
Transformer TR has primary to secondary turn ratio of n:1. Total leakage inductance of the transformer referred to primary is L lk. The voltage across the primary winding of transformer is V AB and the voltage across the secondary winding is V S. D r1 - D r4 are the diodes on the secondary side forming full bridge rectifier circuit.

When a digital project has to work with AC mains a Transformer is used to step-down the voltage (in our case, to 24V or 12V) and then convert it to DC by using a rectifier circuit. In a center-tapped transformer the peak inverse voltage is twice as in bridge rectifier hence this transformer is commonly used in full wave rectifier circuits.
Bridge Rectifier A bridge rectifier is used to rectify AC from a transformer with a single winding (i.e. no centre tap) or whenever you need to direct AC current into a single direction. At any one time, two diodes conduct while the other two are switched off. Notice that all the diodes 'point' towards the positive output.
