DC-DC converters are designed to take a single direct current (DC) voltage source, such as a battery, and convert it to one or more lower or higher DC voltage outputs. The V72B5E150BL is a DC-DC Switching Mode Power Supply (SMPS) that is designed specifically for use in electric vehicle onboard charging applications.The V72B5E150BL SMPS is a high efficiency, low cost, three-phase bridge converter capable of operating with input voltages ranging from 200V to 500V DC. It provides a regulated output voltage of 250V DC to the onboard batteries. The V72B5E150BL can be configured to output either a 400V or a 500V DC output. It also has an automotive grade operating temperature range of -40°C to +85°C.The V72B5E150BL is based on an Interleaved Peak Current Mode (IPCM) control topology. This is an advanced control technique that provides fast transient response and high efficiency. The IPCM topology uses two or more bridges, and its operation is interleaved continuously, which creates higher power transfer efficiency.The V72B5E150BL’s advanced switching circuitry enables it to operate at very high switching frequency, up to 300kHz. The high switching frequency also allows for a wide range of choice for component sizes, which leads to a smaller overall form factor and improved reliability.The V72B5E150BL includes a Safety Shutoff function, which protects the vehicle’s batteries from overvoltage. The maximum voltage threshold can be configured to any value up to 500V DC. The Safety Shutoff function is essential for electric vehicle applications, as it ensures that the vehicle’s batteries are not overcharged or damaged.The V72B5E150BL also has an input short-circuit protection feature, which is designed to protect the vehicle’s charging system from high-short circuit currents. The input short-circuit protection feature activates an output disconnect circuit which turns the V72B5E150BL off when a short circuit is detected.In addition, the V72B5E150BL includes a line transient protection feature, which helps to minimize the shock or vibration from power line transients. It also includes overvoltage protection, which helps to prevent the input voltage from exceeding the rated value and damaging the converter.The V72B5E150BL is an ideal solution for onboard EV charging applications. With its small form factor, high efficiency, and range of safety features, the V72B5E150BL provides a reliable source of power for electric vehicle onboard charging.
