Abstract:
The paper subject of research is synthesis and SPICE simulation of a system for frequency control and regulation of series resonant transistor inverter. A characteristic feature of the system is the tracking of an only one synchronization signal. That is the current in the resonance loop. This approach is extremely preferable when the heat station (HF coupled transformer, tank capacitor and inductor) is distanced from the energy unit. Adaptive dead time control is incorporated in the system, which is a function of the current through the switches at the moment of commutation. The control system automatically limits its minimal working frequency, supporting a minimal commutation lead time of transistors, before the zero-crossing of the current through them. This ensures ZVS in the whole frequency range.
