DC DC converters

DC DC converters are electrical devices used to convert one source of direct current (DC) to another source of DC at a different voltage instead of supplying the same voltage as the input. This conversion process is commonly used to power various electrical systems and components in a wide range of applications. One such DC DC converter is the HES100ZE-A1V, which is a high efficiency DC DC converter designed to provide a wide input voltage range and excellent electrical isolation.

Application Field

The HES100ZE-A1V is designed for military, aerospace or industrial applications where high efficiency and assured performance are required. As such, it is often used in applications requiring high reliability and clean power, such as communications, computing, missile guidance, medical instruments, cameras, and radars. It is intended for use in environments where shock, vibration, temperature, or humidity is a factor. This makes it suitable for use in a range of applications, from aircraft to spacecraft.

Working Principle

The HES100ZE-A1V is a switching DC DC converter, so it works by efficiently transferring the energy from the input source into the load at the opposite voltage. It does this by using two sets of transistors, one which is switched on and off to transfer power from the input to the output, and the other set which is responsible for rectifying the AC signal into DC. The switching transistors are controlled by a feedback system, which monitors the output voltage and adjusts the frequencies of the transistors to ensure the output is kept at the desired voltage.

The HES100ZE-A1V also features a primary side synchronous rectification. This means that the energy transferred from the input into the output is rectified directly, rather than using a secondary rectification stage, which improves efficiency. This feature also eliminates the need for a linear regulator, allowing the converter to have a low standby power consumption. Additionally, the converter also uses two control pathways to ensure precise voltage regulation and minimal ripple or noise.

Thanks to its high efficiency, wide input voltage range, excellent electrical isolation, and primary side synchronous rectification, the HES100ZE-A1V is a perfect choice for use in military, aerospace, or industrial applications where reliable power is crucial.
