Hello All ,
In this thread I will present tool which is designed especially for researching and developing many devices threated here on the forum. It consists of three different modules(for the moment), and is very flexible. Many different topologies of switching can be easily assembled by combining the modules in different ways and with different setups and configurations. The signal source is a two phase PWM module with combined analogue and digital features. It is based on an enhanced 8bit MC, the PIC16F785 with specific peripherals, like a dual phase PWM module and two hi speed comparators, which are used for analogue duty cycle adjustment with infinite resolution. To overcome the limited period resolution typical for digital PWM devices, an adjustable external oscillator is used to clock the MC, which in combination with the pre-scaler allow an infinite period resolution over a wide range of frequencies as well. The second module is the switchboard, which is designed as single floating switch, which allows to assemble simple Hi or Lo side pulsing, half bridge or full bridge topology, or floating coil shorting as well as multiple other configurations as required.
The third module is the floating driver power supply, which provides a galvanically isolated supply for various switching drivers. In the thread we will discuss different solutions for specific applications. Schematics , images and videos on the development will be released as well as firmware and software solutions for specific requirements.
