Working Principle of the SJPJ-L3

The SJPJ-L3 bridge rectifier works on the principle of converting alternating current (AC) to direct current (DC) voltage. The SJPJ-L3 achieves this by using diodes, which are semiconductor devices composed of p and n-type materials. Diodes allow current to flow in one direction only, from the anode to the cathode. When a diode is in the forward-biased position, current is allowed to flow through the diode from the anode to the cathode creating a voltage drop across the diode. This voltage drop is the direct current or “DC” voltage.

The SJPJ-L3 is composed of an array of three diodes per phase. Each phase of the SJPJ-L3 consists of a single diode bridge, which is composed of six internal diodes connected in pairs in series. The three phases, A, B and C, are arranged in a Wye configuration. The SJPJ-L3 has three independent outputs, which are connected to the output via three pins. When AC voltage is applied to the input of the bridge, it causes the output voltage of the bridge to decrease until it reaches the neutral point of the bridge, which corresponds with the DC voltage of the output.

The SJPJ-L3 is capable of withstanding very high surge and transient current levels, making it an ideal solution for applications that require very high levels of current and voltage stability over a wide range of input voltage. The SJPJ-L3 also provides superior temperature performance and minimized EMI generation. Its advanced thermal management design and high-reliability capacitors ensure long-term reliability and enable the product to handle higher than normal operating temperatures without affecting performance.

The SJPJ-L3 can also be used in applications where precision control of voltage and current is required, such as in the field of power conversion and motor control. The ability to precisely control the power output makes the SJPJ-L3 an ideal choice for these applications.

In summary, the SJPJ-L3 is an excellent choice for high efficiency UPS and inverter applications due to its efficient design, high power density, and excellent thermal dissipation. The SJPJ-L3 bridge rectifier has a wide range of application fields and a variety of features that make it an ideal choice for high efficiency AC-DC and DC-DC conversion applications.
