“…However, the topology in [6] has three stages, which is complicated and the parallel connected structure of Boost converter has the voltage equalization and current balance problems [7]. In recent years, the three-phase pulse width modulation (PWM) converter is applied in the heating power supply to improve the PF and the control performance of the system [8,9]. The topology structures in [8,9] consists of two-stage converters, the first-stage three-phase voltage resource rectifier (VSR) regulates the PF and the second-stage full-bridge converter regulates the output power.…”

As a key element of the silicon growth furnace, the heating power supply plays an important role to form the required thermal field for mono-silicon growth. The performance of the heating power supply system is critical to implement the function, which is determined by both hardware topology and control strategies. In this paper, a novel two-stages soft-switching power supply topology is employed to improve the efficiency of the power supply system. Meanwhile, the robust control methods are proposed for both stages converter to achieve high power factor (PF), low total harmonic distortion (THD) and stable output DC voltage under parameters uncertainty or load perturbation. The simulation and experiment results show the correctness of analysis and the effectiveness of the proposed methods. The robust control strategies combined with the advanced soft switching topology improve the system performance for the practical applications.
