Gate Drive Transformers and Circuits

Posted by on

A gate drive transformer is a transformer that is optimized for transmitting rectangular electrical pulses with fast rise and fall times to activate or deactivate the switching device. Despite various floating channel MOSFET/IGBT driver ICs being available, a transformer-coupled gate drive is still the better option to use for high power applications.

Introduction to Gate Drivers for Power Electronics

Posted by on

A gate driver is a power amplifier that accepts a low power input from a controller IC and produces the appropriate high current gate drive for a power device. As requirements for power electronics continue to increase, the design and performance of the gate driver circuitry is becoming ever more important.

SMPS: Phase-Shifted Full-Bridge Converters

Posted by on

Phase-shifted full-bridge (PSFB) converters reduce switching loss and increase efficiency by phase-shifting the gate signals between the leading leg and the lagging leg switches without additional circuits.

SMPS: Resonant Converters

Posted by on

Demand for smaller electronics (and thus smaller power supplies) continues to increase. Resonant techniques are used to allow for high-frequency operation in switched-mode power supplies, which in turn allows for smaller components.

Intro to Switched-Mode Power Supplies (SMPS)

Posted by on

A power supply takes an unregulated power and converts it into a stable regulated power. Electronic equipment is generally powered by low voltage DC supplies. The source will be either a battery, a combination of battery and DC/DC converter or a power supply converting AC mains into one or more low voltage DC supplies.
