Gate Driver Solutions – Plug ‘n Play Rapid Evaluation and Testing

Power digital systems convert electrical power between Air Conditioning as well as DC forms and also in between DC voltages with really high efficiency, enabling more power to move to the end application. The workhorses of power conversion are the switches: power MOSFETs, IGBTs, Wide Bandgap (WBG) semiconductor gadgets, SiC MOSFETs as well as GaN HEMTs.

That is where the gate drivers been available in; every button has a gate. The voltage on the gate regulates whether the button gets on or off. A gate chauffeur is used to manage the voltage on eviction of the power switch, yet it is more complex than that.

The core features of an entrance vehicle driver are 1) to magnify the logic (on/off) signal from the controller to provide appropriate drive current to transform the transistor on or off at the needed speed, as well as 2) give level moving from the logic to eviction, specifically for high-side transistors. Extra features can include shoot-through protection, under- and over-voltage lockout, over-current discovery, desaturation discovery as well as galvanic isolation. The gate driver option influences effectiveness, option, safety and security as well as reliability size.

ON Semiconductor’s wide portfolio of gate chauffeurs can be made use of in a varied variety of applications such as cell phones and wireless tools to solar inverters and also energy storage.

Gate drive functions are also incorporated into controllers for applications such as PFC or LED lights. Gateway vehicle drivers can come in single, double, high-low, half-bridge, H-bridge, or perhaps three-phase inverter geographies, among others.

To support the quick examination and also screening of gateway motorist remedies, we have established an environment of evaluation equipment. This environment includes a Plug ‘n Play wall as well as a collection of mini-driver boards featuring ON Semiconductor gateway drive solutions.

This analysis system enables the system designer to rapidly compare the vibrant performance of various gateway vehicle drivers with a specific power switch. Eviction resistance, bootstrap components and also gate tons can be changed to maximize the changing profile.

The mini vehicle driver boards are self-contained entrance motorist remedies, including one or more ON Semiconductor devices (Number 2).

These boards are designed to connect directly into the baseboard or to be quickly replaced right into an existing application board. Figure 3 programs several configurations where the mini motorist board is attached to drive a switch in a TO-247 bundle.
