Single phase, half wave, controlled, electronically commutated rectifiers, also known as S1GHE3/5AT, are used in power conversion and control devices such as switch-mode power supplies (SMPS) and variable speed drives (VSD). These rectifiers have been developed to provide a robust and reliable solution to high power electronic applications.

The structure of S1GHE3/5AT rectifiers is based on the traditional bridge rectifier configuration. It consists of four parallel connected thyristors (SCRs) and two additional series connected diodes. The additional diodes are used to improve the reverse voltage capability of the rectifier.

The S1GHE rectifier is designed to work at relatively high power levels, typically up to 600 Amps and with voltage levels up to 1200V. The device can be used for AC input voltages of 400 to 600V AC, with a frequency of 50 or 60 Hz. It has an average forward current of up to 600 Amps with peak current up to 800 Amps.

The S1GHE3/5AT rectifier has two main modes of operation. The first is the “free-wheeling” mode, which is used when the mains voltage is present. In this mode, the controlled rectifier acts as a diode, allowing the current to pass only in one direction (forward) and blocking the current in the opposite direction (reverse). The second mode is the “commutation” mode, which is used when the mains voltage is not present. In this mode, the SCRs in the rectifier are switched on and off to control the transfer of current. This process is known as commutation.

The controlled rectifier can be controlled by a variety of different methods, including analogue and digital control. In general, the ability to control the rectifier gives the user more control and flexibility over the power conversion process. For example, the rectifier can be used to adjust the amount of current passing, the level of AC mains voltage, and the input frequency.

The S1GHE3/5AT rectifier is usually used in applications such as motor drives, electric vehicle traction control, UPS systems, electric battery charging, power distribution systems, and electric welding. The device has a relatively high efficiency and provides excellent thermal performance, which makes it suitable for a variety of applications.

In conclusion, the S1GHE3/5AT single phase, half wave, controlled, electronically commutated rectifier is a reliable and robust solution for high power electronic applications. It is suitable for use in a variety of applications, including motor drives, electric vehicle traction control, UPS systems, electric battery charging, power distribution systems, and electric welding. The rectifier can be controlled by multiple methods for greater flexibility and control over the power conversion process.
