System-on-programmable-chip-based versatile modulation architecture applied to domestic induction heating

The development of ad-hoc control architectures is a time-consuming task which is often required to design and evaluate power converters. In this paper, an FPGA-based versatile control architecture test-bench which enables to evaluate and implement different control strategies applied to different power converter topologies is proposed. It is based on a hardware/software codesign by means of MicroBlaze softcore processor and several specific-application peripherals, resulting in a system-on-programmable chip solution. As a result, the control platform combines the versatility of software with the suitability of specific purpose hardware. The architecture proposed in this paper can be applied to the development any power converter design. Nevertheless, this paper is focused on the domestic induction heating application. A complete development test-bench has been carried out and the proposed architecture has been tested through an induction heating power converter prototype.
