AC DC converters are devices that convert AC power to DC power or vice versa. The BB-MDR-40-24 series utilizes a unique patented high frequency pulse width modulation (PWM) design which was developed specifically for the automotive industry and is capable of providing a wide range of power ratings from 10W to 200W.

The BB-MDR-40-24 AC/DC converter utilizes a ferrite-based half-bridge topology with an integrated dc-dc controller powered by the conversion of an input voltage from 24V. This high efficiency design has a power factor correction of greater than 0.9 and a total harmonic distortion of less than 1%.

The BB-MDR-40-24 AC/DC converter is well-suited for a variety of automotive applications, including automotive battery charging, starting systems, DC auxiliary supply, and DC power supply. Furthermore, it can also be used in recreational and marine vehicles, as well as other specialized applications.

The working principle of the BB-MDR-40-24 converter is based on the difference between the voltage at the input and the output, and then it uses a Pulse Width Modulation (PWM) to adjust the output to meet the required input parameters. The PWM is a control method that changes the duty cycle of the signal applied to the device in order to reduce the output from the device by improving the efficiency.

When voltage is applied to the BB-MDR-40-24, the controller divides it into two phases for each half-bridge. The controller then adjusts the duty cycle of each half-bridge so that there is a balanced load across the bridge. As the load connected to the bridge changes, the controller dynamically adjusts the duty cycle to ensure that the input voltage matches the output voltage requirements.

The converter also features integrated fault protection, including: overvoltage, overcurrent and short circuit protection. In addition, it has adjustable operating frequency, allowing for high switching speed, and low ripple noise on the output. Additionally, the BB-MDR-40-24 has EMI and conducted noise filters and transient suppression, allowing the converter to meet stringent automotive emission and electromagnetic compatibility (EMC) requirements.

The BB-MDR-40-24 is an efficient and cost-effective solution that can be used for various automotive applications. It features a high frequency PWM control, adjustable operating frequency, integrated fault protection, EMI and conducted noise filtering, and transient suppression. This makes it an ideal solution for automotive battery charging, starting systems, DC auxiliary supply, and DC power supply applications.
