S8055R67 application field and working principle

A silicon-controlled rectifier (SCR) or thyristor is a semiconductor device with three or four layers of alternating P and N-type materials. SCRs now form the basis of power control in a wide array of applications, including variable speed drives and other power control circuits. SCRs are components that allow voltage and current control during certain periods of operation.

The S8055R67 is a 2-phase 3-level converter integrated with a gate driver (IPR3728) and is designed for applications like AC-DC-AC, DC-DC, and AC-DC-AC inverters. Theswitch combination of the S8055R67 provides symmetric current commutation to the motor and low switching losses due to its wide DC voltage range.

The S8055R67 consists of three thyristors (SCR) for each phase leg. The conduction module provides short-circuit protection for a short period of overcurrent and has a high turn-off capability for additional flexibility in the power application. The reverse blocking capability of the switch allows for balancing the conduction losses and prevents any false commutations due to voltage drops from the supply.

The gate drivers of the S8055R67 can operate up to a LED speed of >10kHz, which helps reduce the noise level of the inverter. The module also has a on-state resistance rating of approximately 2.5 mohms, which provides low power losses during normal operation. The high power rating of the module also ensures long life in the application.

The S8055R67 thyristor module is an important tool for power control applications. It provides reliable and fast switching capability due to its high peak current rating, integrated protection features, and wide input voltage range. The integrated gate drivers and adjustable turn-off times also allow for increased safety and total control of the system. The S8055R67\'s compatibility with a variety of control signals and broadly used current and voltage ranges allows for its use in most applications.
