Mosfet & Diode -> SiC Mosfet

SiC (Silicon Carbide) MOSFETs are power transistors built on a wide-bandgap semiconductor that delivers significantly better performance compared to traditional silicon devices. With the ability to operate at high voltages, very high temperatures (beyond 175-200 °C), low on-resistance (RDS(on)), and greatly reduced switching losses, SiC MOSFETs enable smaller heat sinks, enhanced energy efficiency, and more compact system designs. They are well-suited for demanding applications like solar inverters, EV charging stations, industrial power supplies, and motor drives.

Mosfet & Diode -> Soft Recovery Diode

Soft Recovery Diodes are designed with a ratio between the reverse recovery time (Trrr) and the current fall time (Trrf) of approximately 1:3. This structure ensures a smooth current transition during switching, helping to reduce voltage spikes caused by high current variations (dI/dt) in circuits with inductance, including parasitic inductances. Thanks to their soft recovery behavior, these diodes minimize electromagnetic interference (EMI) and enhance system reliability, making them ideal for use in converters, inverters, and switching power supplies.

Mosfet & Diode -> Fast Recovery Diode

Fast Recovery Diodes (FRD) are designed for high-speed switching applications such as DC/DC converters, power factor correction circuits, motor control, and other high-frequency PWM systems. These diodes can quickly return to their non-conducting state, minimizing losses and voltage spikes during switching.

“Fast” and “ultrafast” diodes are characterized by their ability to stop conducting in the reverse direction very quickly. The term “Soft Recovery” refers to a subset of fast recovery diodes that return to the off state gradually, reducing electromagnetic interference (EMI) and improving circuit reliability.

Power Module -> 3-Phase Diode

The 3-Phase Diode allow to improve the voltage and current waveforms both on the mains side (current closest to a sinusoid) and on the load side (more constant voltage). The most used configuration is the bridge one. Configurations can be:
- Half-wave rectifier
- Full wave rectifier (bridge)
There is also the controlled version, in which the diodes are replaced by thyristors. In this case the thyristors are used to differentiate the output voltage by varying the firing angle (or firing delay). The main application of these rectifiers is in the speed control of DC motors.

Diode -> Triac -> High Power

IGBT - Triac - Rectifier Bridges -> IGBT

IGBT (Insulated Gate Bipolar Transistor) are power electronic devices that combine the advantages of MOSFETs and BJTs, offering high switching speed and the ability to handle high currents and voltages. These devices are ideal for applications such as DC/AC converters, inverters, switching power supplies, and motor control.
