In the production of high-frequency generators, IGBT modules (Insulated Gate Bipolar Transistor) are a good alternative to power MOSFET, generally used by the majority of companies in this field. They offer several advantages, such as less occupied memory on electronic cards, less components and smaller package dimensions, thus improving the efficiency and results of the system while reducing its cost. More technically, IGBT are high-voltage, driver-controlled switching devices, which combine MOSFET's elevated input impedance with low ON state commutation losses typical of bipolar transistors.

In order to employ IGBT in ultrasonic cleaning, the choice and programming of the driver is crucial, as it regulates impulse speed and, at the same time, prevents overloading and short circuits.

MORONI chose a 32 bit MICROCHIP microprocessor which, among other tasks, can pilote the driver. This is why MORONI, unlike other manufacturers, is now able to employ IGBT modules in MOG generators.

Therefore, we can now achieve 120 A to 600 V power - an unconceivable result until 2 or 3 years ago.
