Flexibility thanks to modular design of latest gate driver solutions

Power modules are widely used for power conversion, for example, in the field of renewable energy, automotive, traction, industrial equipment with inverters, UPS and air conditioning. In this context, the efficient control of the modules is of great relevance.

Modular Gate Driver Solutions

As an established manufacturer of current sensors, power modules as well as winding goods, TAMURA now also offers gate driver solutions such as Mitsubishi. The design is modular and offers the possibility to use single components or the complete solution.

Since the IGBT and SiC MOSFET technologies require different gate voltages, Tamura offers coordinated variants for this purpose: +15V/-15V, +15V/-10V as well as +18V/-4V, +18V/-2V. The DC-DC converter stabilizes the two gate voltages by an internal control loop and offers an input voltage range of 13VDC to 28VDC - instead of the usual, limiting 15VDC. With a low-profile design of 12.5mm and a dielectric strength of 5KV, the DC-DC converter allows for optimal use.

The low impedance of the TAMURA Gate Driver eliminates the frequency oscillation of Vce, Ic and VgeL. This makes the Gate Driver extremely reliable, as the stray capacitance (typ. 12pF) is very low. To ensure high reliability in interference-prone, demanding environments, TAMURA has built the latest generation with a capacitive isolation system. This isolation method has several advantages compared to isolation using optocouplers:

• Longer life with less loss of efficiency
.
• Shorter propagation delay
.
• Nearly equal rise and fall times
.
• Less susceptible to magnetic noise

For the highest requirements, TAMURA offers the Gate Driver Unit. In addition to the DC-DC converter and the gate driver module, this complete solution also includes a printed circuit board with the required gate resistors and protective circuits (including undervoltage lockout, short circuit protection, desaturation protection) that is matched to the respective power module.
