Introduction

S1GBHM4G is a single phase gleichrichter bridge rectifier with a diodes rating of 1000 V and 0.2 A. It is a three-terminal device, consisting of a gallium arsidenide diode and a silicon controlled rectifier (SCR). It is used in applications such as motor speed control, line-feeding rectification and motor feed-back control.

Applications

S1GBHM4G rectifiers are used in a variety of applications, including motor control, line-feeding rectification and motor feed-back control.For motor speed control, the device is used in combination with an AC to DC conversion and a current sensitive switching regulator such as an SCR, switchmode or pulse-width modulator. The rectifier can be used to convert the input AC power to a DC power source and regulate the current, enabling electronic speed control of the motor.For line-feeding rectification, S1GBHM4G is used to provide a DC bias for a power conversion system, such as a transformer, for line feeding. The rectifier can provide both a DC voltage output and a DC current output depending on the application.Lastly, the device can be used in motor feed-back control, in order to control the power supply current to a motor or other load device. It can be used to provide a reference voltage to a current regulator device, such as a voltage or current reference.

Working principle

S1GBHM4G rectifiers are composed of two components: a gallium arsenide diode and a silicon controlled rectifier (SCR). The diode is used to convert AC input current to DC output current, while the SCR is used to control the current.The diode rectifies the incoming AC current into a pulsed DC output. This output is then smoothed out by a capacitor and then applied to the SCR, which will regulate the amount of current and voltage applied to the load.When the SCR is “on”, it acts as a regulator and ensures the current flow and output voltage are maintained at the desired value. When the SCR is “off”, no current is flowing and the capacitor maintains the voltage stored in the system.

Conclusion

S1GBHM4G rectifiers are three-terminal devices that can be used in a variety of applications, including motor speed control, line-feeding rectification and motor feed-back control. The rectifier is composed of a gallium arsenide diode and a silicon controlled rectifier (SCR), which together allow for the conversion of AC to DC and the regulation of current and voltage. This makes them an ideal solution for applications requiring a steady supply of power and current.
