Updated: 200A 1.2kV bidirectional switch module built around novel semiconductor

Ideal Power is aiming to compete with smart IGBT modules, with a 1.2kV 160A (100°C, 240A at 25°C) power module built around its novel ‘B-Tran’ bi-direction semiconductor switch.

Called IPA01216DFx-HS, it comes in an industry-standard 62mm package which includes an isolated driver circuit and “has significant advantages compared to IGBT modules, including lower losses and inherent bidirectionality”, according to the company.

Update:

The module is designed to replace back-to-back IGBTs and has two inputs – IN1 and IN2 (diagram left) that are intended to be driven in a similar fashion to the two IGBTs gates (chart below).

“IN1 and IN2 are the only logic level inputs that are needed to control the switching of the device,” the company told Electronics Weekly. “IN1 and IN2 mimic the standard G1 and G2 in a common emitter/common source IGBT or mosfet module.”

The secondary side of the module needs a 12V supply on VDRV, through which up to 6A is drawn when the device is turned on ‘on’ using IN1/IN2.

“6A is the max current at full power,” said Ideal. “The internal integrated driver regulates the drive current as needed to drive B-Tran device. The customer has an option to reduce the drive power in case of light load condition by providing an external signal to the power module.”

The primary side needs 12V at 100mA and a PWM logic signal of 3 to 12V in amplitude (12V recommended).

Switch-wise, saturation voltage is 0.6V (0.8Vmax) with 160A flowing (Tj=25°C), and use is expected up to 35kHz (≤20Khz recommended).

Turn on and off delays are 20ns and 100ns respectively, then rise time is 60ns and fall time 200ns. Turn on and off energy is 1.7 and 4.3mJ.

Over-current protection, under-voltage protection and temperature sensing are included.

“The introduction of our second product marks another commercialisation milestone for Ideal Power and our technology,” said Ideal CEO Dan Brdar. “We look forward to our first commercial sales from this product next year – We are introducing products at a time when renewables, energy storage and electric vehicle charging are in the early stages of adoption. OEMs are looking for more efficient power semiconductors to improve the efficiency of their products.”

Ideal Power is based in Austin Texas.
