Having the correct and proper enclosures, is a mechanical (and also a marketing) problem many electronics projects suffer from. It is also related to anticipated sales numbers. For big numbers, a custom enclosure which is produced with an injection molding machine is not a big cost since the financial burden can be divided and written […]
Finally, we are almost there. Our first product – a joint development result of cooperation between IACS and RTOS.BE – is about to be commercialized. The Energy2Switch is a DC switch board with 2 channels rated up to 50V and 40A. Continuous power is limited at 1500W per channel, which boils down to 40A @ […]
Introduction A few months ago – as a prototyping experiment – we decided to develop two types of high-power switching boards: one for high-side switching and another one for low-side switching. Goal was to gain some experience on different switching techniques for charge controllers. We contacted several hardware development / prototyping companies and, at the […]
The ADC is a much used peripheral in embedded systems. This is not different in our project. We extensively use it to read out – for example – voltage and amperage data. Many people are still unaware of the fact that it is still just sampling: One gets a digital value which is the result […]
In order to charge batteries with the wind turbine simulator, the setup already becomes quite elaborate. First, there is the brushed DC motor which drives the axial flux turbine. It has a 24V, 350W and maximum 19A rating. The DC motor drives the generator with a chain gear to step down the high RPM of […]
Introduction The core of our charge controller (PMD2) is essentially two switchable mosfet channels: one channel to load a battery (bank) and another channel to divert abundant energy to a dump load. Both channels can be switched on/off by software controlled PWM, and by configuring different PWM duty cycle ratios, we should be able: to […]
One of the challenges involved in designing and developing the ‘energy harvester‘, is to work out how to design, prototype, test and evaluate software algorithms for managing power flow in the system. At first, we can use powerful lab power supplies: We have lab supplies capable of 900W, 1500W and 3000W DC power output. These […]
Attopilot 50V 180A A few weeks ago we tested the Attopilot 50V 90A. Results were ok, we only noticed a small gap between measured and real amps. Today we show you the experimentation results of the 180A Attopilot sensor board. Again, we used the Deans connectors and quite a lot of solder to connect the Attopilot device […]
The energy harvester application needs to be able to determine current flows and volt charges in order to take the right decisions about charging and dumping. The micro-controller’s ADC unit is able to translate the analogue signal from the sensor into a quantified entity, a number if you wish. Internally, the device current is limited […]
Prototype building block While working on our energy harvester design, we have identified a couple of relatively independent building blocks that could also be interesting for other people doing projects and building prototypes. One building block is the switch: In its most basic form, it closes an electrical circuit after which a load can get […]
