Diodes are two-terminal electronic components that allow current to flow in one direction. A rectifier is a type of diode that allows only current to flow in one direction, and can be used to create a DC voltage from an AC voltage. An array of diodes connected together, sometimes referred to as an integrated bridge rectifier, is commonly used to control voltage levels and provide protection against over-current events. The UGF2004G C0G rectifier array is an example of such a device, and this article will discuss its application field, as well as its working principle.

The UGF2004G C0G is a four-channel rectifier array rated for 10kV, making it suitable for high-voltage applications such as electric power distribution, agriculture power control systems, industrial switching, and other applications. It features very low leakage current, high rectification efficiency, and excellent temperature stability, making it a reliable choice for these types of applications. Additionally, it has a relatively fast response time, making it highly suitable for use in pulse width modulation (PWM) circuits.

The most common application for the UGF2004G C0G is for alternating current (AC) to direct current (DC) conversion. This is achieved by connecting the rectifier array in series with an AC voltage source, with the four channels operating differently depending on the AC voltage’s polarity. When the AC voltage is positive, two of the rectifier channels will conduct electricity in one direction, while the other two conduct electricity in the opposite direction. When the polarity is negative, they switch roles, resulting in DC current passing through the rectifier array. This is known as a full-wave rectification circuit.

The UGF2004G C0G is also useful for preventing over-voltage in a system by providing an indirect path for excess current to flow. This is accomplished by connecting the rectifier array in parallel with components that require protection. When an over-voltage event occurs, the rectifier array channels will open, allowing excess voltage to flow through the array rather than the protected component. This prevents the component from suffering damage due to an over-voltage event.

The UGF2004G C0G is also employed for controlling and regulating the output current of an AC power supply. This can be accomplished by connecting the rectifier array in series with the output of an AC power supply, with the rectifier array connected in such a way that it conducts only half of the pulses from the AC power supply. This reduces the output current amplitude to a manageable level, making it safe to use for the components connected downstream.

In conclusion, the UGF2004G C0G is a rectifier array designed for use in high-voltage applications where a reliable and efficient rectifier is needed. It can be used for AC/DC conversion, voltage control, preventing over-voltage, and regulating output current. Its features, such as low leakage current, high rectification efficiency, and excellent temperature stability, make it an attractive option for a variety of applications.
