MEV1S0505DC

DC DC Converters

DC/DC converters, also known as DC/DC switches, are a versatile and affordable class of product for widely varying applications, ranging from energy saving light bulbs to military aircraft and radar systems. MEV1S0505DC is a popular series of DC/DC converters and the purpose of this article is to examine its specific application field and working principle.

Application Field

The MEV1S0505DC series of DC/DC converters feature high efficiency, wide input voltage range, and wide temperature range, making it an excellent choice for numerous mission-critical applications like signal conditioning, avionics, and medical device applications. It is particularly well-suited to automotive applications due to its built-in OVP (over voltage protection) and UVP (under voltage protection) design. As a 50V output, 5A maximum DC/DC converter with a wide range of switching frequencies, the MEV1S0505DC series is also suitable for motor control systems, portable military batteries, and unmanned vehicles.

Working Principle

The MEV1S0505DC series use an imput bridge rectifier (IBR) and a buck switching converter (BSC) to convert an incoming AC voltage to a stable, adjustable DC voltage. The IBR converts the alternating current (AC) into a direct current pulse, leading to the application of the pulse modulation principle. The IBR stores a certain amount of charge on a capacitor. When the capacitor voltage reaches the high level, the transistor switch is turned on and current flows in the load. When the voltage drops to a low level, the transistor switch is turned off and current is cut off from the load.

The BSC is commonly used in cell phone chargers and RF amplifiers to convert high DC voltage to adjustable low DC voltage. The MEV1S0505DC series also use the BSC to regulate the output DC voltage from a fluctuating AC input voltage. When the input voltage is greater than the output voltage, the switch is turned on and current flows through the inductor. When the input voltage is lower than the output voltage, the switch is turned off and the inductor stores the energy until the switch reopens.

Conclusion

The MEV1S0505DC series are a versatile and cost-effective range of DC/DC converters, suitable for a wide range of applications, from energy saving light bulbs to automotive applications and military aircraft and radar systems. In these applications, the MEV1S0505DC series employ an IBR to convert an incoming AC voltage to a direct current, and a BSC to regulate the DC voltage from a fluctuating AC input voltage. Built with OVP and UVP design, the MEV1S0505DC converter meets the needs of today’s mission-critical applications.
