The complexity and the associated requirements for power electronics in the industrial and automotive sector are constantly increasing. This makes the search to find the right high-voltage DC-DC converter for the respective application considerably more difficult. In addition to properties such as size and weight, the required input and output voltages are decisive. The power to be provided and other variables also play a role when selecting the right high-voltage DC-DC converter. Only by taking these into account can you find the right high-voltage DC-DC converter and the ideal on-board power supply solution.
Environmental conditions
Depending on the area of application, the high-voltage DC-DC converter is exposed to various environmental influences. These include temperature fluctuations, vibrations or humidity. An appropriate protection class and suitable component selection are crucial to ensure reliable operation and prevent premature failure. Finding the right high-voltage DC-DC converter can mitigate these risks.
Efficiency
The efficiency or standby consumption of the high-voltage DC-DC converters installed in the system is very important. This is true for the operating costs, the range of a vehicle or the thermal behaviour. It is important not only to consider the value specified by the manufacturer at the ideal operating point. Instead, examine the behaviour of the voltage converter over the entire load range relevant to the application. By doing this, you can ensure you find the right high-voltage DC-DC converter for your needs.
Thermal behaviour
Efficiency alone says little about whether a voltage transformer in a car is suitable for an application. Even a very high level of efficiency can lead to enormous heat development under corresponding load conditions. This may require a reduction in power, a so-called derating, or a shutdown of the converter. Therefore, heat dissipation plays a decisive role in power electronics. This is ensured, for example, by contact cooling, the use of fans or liquid cooling. This should always be considered when you find the right high-voltage DC-DC converter.
Certifications
Depending on the intended use and location, the high-voltage DC-DC converters must have different certifications. It should be clarified with the manufacturer at an early stage whether the desired DC-DC voltage converter has the necessary approvals for the application or whether it can fulfil them. Finding the right high-voltage DC-DC converter with the correct certifications is essential.
Sustainability
Increasing environmental awareness is putting the sustainability factor more and more in the focus of governments, the population and companies. For this reason, aspects such as production, materials used, reusability, packaging and repair options should also be taken into account. This is crucial when choosing a DC-DC voltage converter to find the right high-voltage DC-DC converter.
Integration
Due to the high complexity of the individual components, integration into existing systems is becoming more challenging. Controllability of the high-voltage DC-DC converter by switching cables, the interlock, the communication interface and the power connectors are key factors. These factors are important in system integration, where compliance with current valid standards should be ensured. Thus, it is crucial to find the right high-voltage DC-DC converter that meets all integration requirements.
