Abstract

In many industrial applications we need small dimensions dc-dc power convertors with a high integrated scale circuit. A lot of applications require ability to be connected at different DC power supply sources. In this scope we are using dc-dc power convertors. This power convertor requires a large input supply voltages and also the drop voltage over power converter must be as small as possible. In these days it is possible to achieve this goal by using high integrated scale microcontrollers and small power MOSFET transistors. The new microcontrollers have enough computing power to ensure a fast application response and they integrate a lot of hardware modules (analogue to digital converters, timers, pulse width modulation modules) that allow us to minimize the schematic. The new MOSFET transistors are able to support high voltages and they can be driven with low control voltage. This new advantage recommends them to be used in power applications. The schematic is very simple and all the control and computation algorithms are implemented in microcontroller software. The microcontroller requires a low power consumption. The schematic is implemented using surface mount technology in a single module. The module dimensions are very small. The power module recommends to be used to power a lot of electronic modules, electric devices (like inductors, valves i.e.) for industrial automation and operation.
