Application Field of V3PAL45-M3/I

V3PAL45-M3/I is a single phase three-level half-controlled bridge rectifier module. It is primarily used in the battery charging and discharging applications, and can be applied in the energy storage industry. The rectifier module can handle direct current input up to ±35V, and can both charge and discharge up to ±10V to the battery easily. This makes V3PAL45-M3/Iqualified for various battery energy storage systems, AC/DC converters, and DC/DC converters. The module is also very efficient in operation, with soft-start power dissipation as low as 1.4W and a 5ms charge/discharge cycle. The rectifier module is designed with a built-in temperature protection to ensure its safe operation under high temperatures, and is capable of providing reliable and continuous power up to a working temperature of 85°C. Additionally, its design makes it suitable for space-limited applications, and its highly safe half-bridge structure allows it to withstand a breakdown voltage of up to 400V.

Working Principle of V3PAL45-M3/I

V3PAL45-M3/I is a half-bridge rectifier, which means it can charge both sides of the battery while discharging one side. The device consists of a rectifier bridge, a voltage detection circuit, a protection circuit, and a control circuit. The rectifier bridge is made of four diodes, two of which form a "half-bridge". The other two diodes are used to form a full bridge when all four diodes are in reverse-bias. The rectifier bridge consists of four diodes in a purely diode-connected bridge, meaning no transistors are used to control its operation. The working principle of V3PAL45-M3/I is to convert the alternating current from the grid into direct current and feed it to the battery. This process is done by the half-controlled rectifier bridge, which switches between its two states, depending on the input voltage. When an input voltage above zero is supplied to the module, the first two diodes in the bridge become forward biased, and current will flow through the DC-link to the plus-side of the battery. At the same time, the second two diodes become reverse biased, thus, no current flows to the minus-side of the battery. This process continues until the input voltage drops below zero, which will cause the second two diodes to become forward biased, and the current will flow to the minus-side of the battery.The voltage detection circuit in V3PAL45-M3/I continuously monitors the output voltage of the module, and when the module is over-voltage or under-voltage, it will turn off the module\'s operation, thus protecting the device from any damage. This makes V3PAL45-M3/I perfectly suitable for energy storage applications. The protection circuit of V3PAL45-M3/I is also quite useful. It prevents over-voltage, under-voltage, and over-current, thus ensuring the safe and reliable operation of the module. Finally, the control circuit of V3PAL45-M3/I constantly monitors the input power and switches the two diodes in the bridge accordingly. It also allows the user to set the charging and discharging parameters as per their needs. To sum up, V3PAL45-M3/I is an efficient and reliable rectifier module designed for battery charging and discharging applications in the energy storage industry. Its half-controlled bridge rectifier design makes it capable of providing a smooth and steady flow of direct current, and its built-in protection circuits ensure a safe and reliable operation.
