Working Principle

The VBO 21-12NO7 is a full-wave bridge rectifier. This is achieved by connecting two, or four, semi-conductors together with diodes in the same package. The result is four diodes arranged in a bridge or “cross” shape, to form the rectifier. The bridge configuration means that the full AC input is rectified and the output is DC. This allows AC signals to be rectified with little or no distortion and with high efficiency.

The bridge rectifier can handle both symmetric and asymmetric loads, depending on how it is connected to the AC source and the load. When connected to an AC source, the current will flow through the two semiconductor components and the two diodes in each arm of the bridge. These two diodes will then convert the AC into DC by switching on and off alternately. When connected to a load, the diodes will control the output voltage via the capacitors in the bridge and can also control the duty cycle of the output voltage.

The VBO 21-12NO7 is available in a variety of case sizes, which depend on the application. Large high-voltage and high-current applications typically require larger case sizes to accommodate the higher operating voltages and currents. In addition, the bridge rectifier requires a heat sink in order to dissipate heat and ensure proper operation.

In summary, the VBO 21-12NO7 bridge rectifier offers superior electrical performance and reliability for a variety of power applications. Its wide range of case sizes makes it suitable for a wide range of applications and its ability to implement powerful semiconductor protection features makes it an excellent choice for powering systems that require high levels of electrical safety.
