Circuit Block for Power Electronics

A single unit of this product can function as a DC/DC converter. Various types of power converters can then be realized by combining multiple units. For example, connecting two units together results in a single phase inverter while connecting three units together results in a three-phase inverter.


Circuit Block for Power Electronics

Circuits that are the core of power electronics technology (Power conversion via switching operations)


● This product is a circuit block that utilizes Rohm’s new trench type SiC-MOSFETs ”SCT3030AL”.

● This product contains two SiC power devices and a gate drive circuit and consists of a circuit board, heat sink, and fan.

● This product can receive external gate signals that drive each SiC power device and can also utilize external power.

● A separately provided external electrolytic capacitor, 24V and 5V power supplies, wires between circuit boards, and a controller are required to utilize this product.

● The control circuit and power circuit were designed to be insulated.

● This product has protective functions against arm short-circuits and undervoltage in the gate drive circuit and hence does not easily break, even when the gate pulse pattern is incorrect.


Research and development applications

● As evaluation samples for researchers already utilizing SiC power devices

● As sample evaluation circuits for researchers considering the use of SiC devices

● As evaluation circuits for parts manufacturers developing new peripheral circuits incorporating SiC devices

Product prototype applications

● As the circuit to be built in prototypes of products

Product built-in applications

● As the circuit to be built in mass-produced products

* Specific built-in applications can include power storage systems, power converters for V2H (Vehicle to Home) equipment, and PCSs for renewable energy.
