A new podcast exploring power electronics as it really behaves in the field
PowerDive by Premium Psu, a new bimonthly podcast created for engineers, system integrators and technical professionals working with power conversion in demanding environments. The goal: provide clear insights, real-world context and field experience in a domain where reliability, margin and stability define the success of a design.
The first episode dives into a topic that looks simple on paper but becomes a real engineering challenge in practice: the gap between nominal values and real operating conditions in critical applications.
When “nominal” stops being the norm
Voltage drops, spikes, fast transients and unpredictable fluctuations are common in the field. While they may appear exceptional in laboratory conditions, they occur frequently in railway systems, industrial installations or battery-powered architectures.
When power architectures are built around ideal or nominal values, these variations quickly become a source of instability.
For system integrators, the consequences often appear late in the process:
- during validation,
- or even after deployment.
Unexpected resets, unstable behaviour, thermal stress or last-minute changes to the power architecture can erode the original design margin in a matter of days.
The first episode of PowerDive focuses precisely on understanding why this happens, and why designing only for the nominal point is rarely sufficient.
Wide input range: beyond the datasheet
The podcast highlights a key message for engineers:
a wide input range is not just a specification — it is a design mindset.
a wide input range is not just a specification — it is a design mindset.
Treating the input range as a real operating envelope rather than a theoretical value means anticipating variability, not reacting to it. At Premium PSU, this philosophy guides the development of our wide-input DC/DC solutions, which are engineered to maintain:
✔ Stable output regulation, even during temporary bus voltage drops
✔ Consistent efficiency throughout the full input and load range
✔ Real thermal margin, ensuring dependable operation under varying conditions
✔ Predictable behaviour, both in validation and in the field
✔ Consistent efficiency throughout the full input and load range
✔ Real thermal margin, ensuring dependable operation under varying conditions
✔ Predictable behaviour, both in validation and in the field
This approach is essential for environments where voltage conditions rarely align with the nominal value shown on a datasheet.
A clear example: the CLS family of railway DC/DC converters
A practical illustration of this design mindset is the CLS family, a series of DC/DC railway converters engineered to handle real operating scenarios in applications such as HVAC systems, signaling equipment or onboard electronics.
These converters are designed to maintain stability across wide and fluctuating input voltages, helping system designers preserve electrical and thermal margins, reduce redesign risks and reinforce overall system robustness.
The episode explores why architectures built with this philosophy tend to perform more reliably when conditions deviate from the ideal.
Designing for the extremes, not the ideal
Throughout the conversation, the guest expert explains why the real performance of a power system is defined by its behaviour at the extremes — not at the nominal point.
The episode covers:
- why nominal voltage is rarely stable in the field;
- how fluctuations affect regulation, efficiency and thermal performance;
- the risks of underestimating input variability;
- why robust simulation and stress testing are essential;
- and how wide-input solutions prevent redesigns and delays during deployment.
The underlying message is clear: power systems fail in the real world, not in the datasheet.
A new space for knowledge and practical insight
With the launch of PowerDive, Premium PSU opens a new channel for sharing the challenges and insights that define modern power electronics. Every two months, the podcast will bring new discussions, technical perspectives and real use cases to help engineers design with margin from day one.

After 15 years leading Premium PSU, Jordi Gazo steps aside to become Non-Executive Chairman, leaving his position as CEO. The company now begins a new stage under the leadership of Ezequiel Navarro, who brings a clear vision: to drive international expansion, boost innovation, and strengthen Premium PSU’s presence in high-growth markets.
A Leadership Transition for Continued Growth
Over the past 15 years, Jordi Gazo has played a key role in Premium PSU’s growth and consolidation as a reference company in advanced power supply solutions. In his new role as Non-Executive Chairman, he will continue to provide strategic guidance and support, contributing his deep industry expertise.
Ezequiel Navarro takes on the position of CEO with an impressive background in industrial and technological leadership. He served as CEO of Grupo Premo for 18 years and is currently Non-Executive Chairman of Innova IRV, where he promotes innovation and business development initiatives. He has also been a member of the Premium PSU Board for the past three years, and in recent months has collaborated closely with the company as a strategic advisor.
A Customer-Centric Vision and a Global Outlook
In his first remarks as CEO, Navarro shared his vision for the company’s future:
“We want to be the best in power supplies. Premium PSU has the potential and structure to become a 50 to 100-million-euro company. Our focus will always be on putting the customer at the center.”
With a firm commitment to internationalization, technological innovation, and customer proximity, Premium PSU aims to strengthen its global footprint and continue developing high-performance power supply solutions for demanding industries worldwide.
Looking Ahead
The appointment of Ezequiel Navarro marks the beginning of an exciting new chapter for Premium PSU. The company remains committed to the values that define it: excellence, innovation, and a customer-first mindset, as it continues to grow and expand internationally.
Premium S.A. has been a beneficiary of European Funds aimed at promoting sustainable growth and the competitiveness of SMEs.
