Introduction

SJPL-D2 is a type of switch mode power supply rectifier suitable for medium and low power applications. It is a general purpose rectifier, commonly used in power supplies of both commercial and industrial equipment. It is a single-phase, full-wave rectifier, and it is designed to be compact, reliable and highly efficient. This article will discuss the application field and working principle of SJPL-D2 rectifiers.

Application Field

SJPL-D2 rectifiers are suitable for most non-high-voltage applications. Examples of applications include low-scale lighting systems, refrigerators, computer power supplies and office equipment. The rectifier is sensitive to temperature and can be used in temperatures up to 85°C. Its peak forward surge rating is up to 1A, making it suitable for medium and low power applications.

Structure and Working Principle

The SJPL-D2 rectifier consists of a main PCB board, a heat sink and two terminal pins. The PCB consists of two large copper plates, which are connected to a thermistor. The thermistor helps to regulate the temperature of the rectifier, preventing it from overheating. The heat sink helps to dissipate the heat from the PCB, keeping the temperature of the electronic components within operational specifications. The two terminal pins are connected to the power supply, allowing the rectifier to be connected to the power supply.When the rectifier is connected to the supply, it acts as a full-wave bridge rectifier. It has four terminals, two of which are anodes and two are cathodes. The two anodes form a single anode terminal, while the two cathodes form a single cathode terminal. This arrangement allows both positive and negative voltages to be applied across the circuit, allowing the rectifier to operate as a full-wave rectifier.When the circuit is in operation, the current flows from the anode to the cathode through the diodes, creating a rectified waveform. The current is then transformed into a DC voltage by a transformer. The transformer is responsible for increasing or decreasing the current levels, depending on the required voltage. In addition to full-wave rectification, the SJPL-D2 rectifier can be used as part of a process to regulate current and voltage levels. In voltage regulation circuits, the rectifier can be used to prevent excessive current from passing through the circuit. In current regulation circuits, it is used to ensure that the current does not exceed the required level.

Conclusion

SJPL-D2 rectifiers are a general purpose, single-phase, full-wave rectifier suitable for medium and low power applications. These rectifiers are highly efficient and are designed to be compact, reliable and temperature-sensitive. They have a peak forward surge rating of up to 1A and can be used in temperatures up to 85°C. When connected to a power supply, they act as a full-wave bridge rectifier, and they can also be used in voltage and current regulation circuits.
