I am a bespoke engineer with Kikusui’s System Technology Group. While earlier in my career I was involved with our standard (off-the-shelf) range, I have now actually spent longer working with bespoke devices. In this series, I discuss various aspects of bespoke engineering.

In this article I will discuss applications for the PBZ series bipolar power supply. One question I get asked a lot about the PBZ series is whether multiple units can be linked in series. The engineer in me is ashamed to have to tell my clients, “unfortunately, no”. However, while referred to as “power supplies”, the PBZ series are effectively a range of power amplifiers. I tried to come up with an elegant solution for boosting their power output. (Readers who are familiar with audio equipment might be able to tell where I’m going with this.)

This feature offers some tips and tricks on using DC power supplies within the scope of ensuring safe use, although they are not mentioned in the Operation Manuals.

How to Achieve Variable Internal Resistance Functionality Easily Using PBZ Series High-speed Bipolar Power Supplies The stabilized DC power supplies sold by Kikusui Electronics are often compared with batteries. In the sense that direct current can be drawn from both, in terms of purely voltage or current, they are the same, but in fact there…
