Precise engineering is essential at every stage of designing a circuit, and it is equally important in the design of the components. One component that must be carefully designed is the gate – drive transformer in a switch-mode power supply (SMPS). Browse high isolation, gate drive transformer products, including SMT and THT mounting options in various package sizes and winding configurations.

There are many types of transformers. What distinguishes a gate drive transformer from other types of transformers?

Basically, it is application! Transformer -Isolated Gate Driver Provides very large duty cycle ratios. DC isolation and either step up or step down capability. Mouser is an authorized distributor for EPCOS. Topologies using a half-bridge configuration.

Основные области применения . I know someone requested I did a video on this so here it is. The all-silicon-solution.

I found a ferrite ring from a microwave oven power. All the details on our product families in the Wurth Electronics catalog Passive Components. What is a gate drive transformer (GDT)?

When you have an inverter, for example an H-bridge, the upper switches (MOSFET, IGBT, whatever) in each leg are floating. Some sort of isolated drive is required. This can be implemented in many different ways, using optocouplers, . VAC products are significant. International safety construction, VDE approved. VRMS gate to drive winding test.

Useful operating frequency from 20kHz to 100kHz. Design procedure for ground referenced and high side gate drive circuits, AC coupled and transformer isolated solutions are described in great details. A special section deals with the gate drive requirements of the. For more information, see the Overview for MOSFET and. MOSFETs in synchronous rectifier applications.

Triad gate drive transformers are used universally in all high frequency switching topologies to isolate the control circuitry from the line-connected switches. Turn ratios of 1:and 1:1. This technique is what the oneTesla product line uses, and is what is typically used on Tesla coils due to its simplicity and reliability.

Typical gate drive waveforms. Ideally we want the waveform at the gate of a MOSFET to be very clean, with steep rising and falling edges, no overshoot, no ringing, and no droop to the tops and . GDT circuit allows the drive signal to the MOSFET to range from down to , while still offering a fast turn-off that cannot be accomplished with a simple load resistor. I do not know the details of your mosfets, so these are general guidelines. You seem to already have a good grip on the important issues: 1) You are correct in assuming 10mH is way too high of an inductance for any switching power supply. H is so high you could use it in audio circuits.

At Agile Magnetics, our vast supply of custom and standard high frequency transformers leads the market in precision, performance, and quality. Gate drive pulse transformers , design tips and examples. Small Form-Factor Reinforced Isolated IGBT Gate Drive Design for 3- Phase Inverter . Designs for Single or Double Eneded Controllers.
