This paper describes a new method for the on-line parameter estimation of an induction heating system. Simulations and experiments are presented in order to measure its impedance matrix for more exact control in closed loop. In previous papers, various parameter identification methods including off-line methods were introduced and compared for current inverters. It has been demonstrated that parameter identification is necessary to achieve good control of the inductor currents. A "pseudo-energy" method for a simple and fast implementation is compared to a classical "V/I with phase shift" method. They are experienced on a reduced power 3-phase coupled resonant system supplied with voltage inverters with satisfying results.

“…When higher output power is required, the third family of topologies derived from the full-bridge converter are preferred. In [19][20][21][22], the association of multiple full-bridge topologies is proposed to implement a multi-inductor structure, with special considerations to the electromagnetic coupling. These topologies provide higher output power at the cost of a higher device number.…”

Flexible cooking surfaces represent the most innovative and high-performance induction heating appliances nowadays. This paper presents a multiple-output resonant inverter for multi-coil systems featuring high efficiency and flexible output power control for modern induction heating appliances. By adopting a matrix structure, the number of controlled devices can be significantly reduced while a high control versatility is ensured. The proposed converter is firstly analyzed and, in order to prove the feasibility of the proposal, a multiple-output prototype is designed and implemented. The experimental results prove the correct converter operation and output power control with multiple induction heating loads, validating the proposed approach.

Resonant power conversion is a key enabling technology for many high performance and high efficiency systems. Induction heating is an example of such systems which outperforms conventional heating technologies, leading to a wide spectrum of industrial, domestic, and medical applications. In order to ensure the proper operation of the resonant converter, accurate converter operation monitoring techniques are required. This paper proposes an effective monitoring technique based on the measurement of the resonant capacitor voltage. The proposed monitoring system provides essential information regarding the output power, soft-switching conditions, and input voltage, while featuring a cost-effective implementation. The proposed technique is validated through an FPGA-controlled resonant power converter applied to induction heating, proving the feasibility of this proposal. 0885-8993 (c)
