A gate drive transformer must reproduce the shape of an input pulse as accurately as possible at its secondary terminals. The performance of a gate drive transformer’s pulse characteristics is specified in terms of its effect on the shape of the pulse input current/voltage. It is important that the transformer must reproduce the shape of...weiterlesen
A gate drive transformer is optimized for transmitting rectangular electrical pulses with fast rise and fall times to activate or deactivate a 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 for many reasons. For example, due to the multiple...weiterlesen
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 are becoming ever more important.weiterlesen
Designing magnetic components for SMPS can be challenging due to the increasing demands of modern electronics designs. Following these 12 steps can help engineers navigate the challenges and ensure a successful projectweiterlesen
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 circuitsweiterlesen
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 componentsweiterlesen
The fourth article in our series on switched-mode power supplies (SMPS) covers the main types of symmetrical isolated converter topologies: push-pull, half-bridge, und full-bridgeweiterlesen
Isolated SMPS topologies are split into two main categories depending upon how the transformer is utilized: asymmetrical and symmetrical. In this article, we discuss asymmetrical isolated converter topologies.weiterlesen
Non-isolated converters are less common than isolated converters among typical switched-mode power supply (SMPS) topologies. But they still have several useful applications.weiterlesen
Switched-mode power supplies (SMPS) are fairly complex compared to linear regulated power supplies. But this complexity results in a stable, regulated DC supply that can deliver power more efficiently for a given size, weight and cost.weiterlesen
