Induction heating (IH) technique has been widely used in industrial and domestic heating applications. In IH cooking applications, multi-output IH systems are increasing in demand. In this study, an inverter configuration is proposed for two-output IH cooking applications. The objective of this proposal is to reduce the component count and thereby the size of the circuit and cost. In this proposed configuration, two IH loads are connected to a full-bridge inverter output and these loads are sharing a common resonant capacitor. The output power is controlled using on-off control. Switching losses are reduced due to zero voltage switching operation. The two loads are independently controlled with high efficiency. The control logic of the proposed system is described in detail and prototype is designed, implemented and the validity is verified through experimental and simulation results.

Battery energy storage systems (BESSs) are being presented as a prominent solution to the various imminent issues associated with the integration of variable renewable energy sources in the distribution system. Performance of grid‐connected BESS depends on the type of application (power and energy), grid operating parameters and level of interconnection point, which shows the necessity of benefit assessment of BESS technology and its applications in terms of economic and grid operations before investment at a larger scale. In this study, real‐time analysis and evaluation of two different battery technologies connected in a medium voltage (MV) distribution system are carried out. The main objective of this paper is focused on the impact analysis of large‐scale BESS on MV distribution feeder. A real case of installation of lithium‐ion and advanced lead‐acid battery systems into the Indian distribution system has been considered for this study. Different operational strategies of BESS such as frequency regulation and energy time‐shift have been performed with real‐time data. The effectiveness in usage of BESS with these functionalities has been verified in terms of peak shaving, improvement in voltage profile and reduction in power losses in the feeder.

Resonant inverters are widely used in induction heating applications. Series Resonant Inverter (SRI) fed with voltage source is very much reliable, cost-effective and provides various power control techniques. Different power control schemes like phase shift control (PSC), asymmetrical duty cycle (ADC) control, asymmetrical voltage cancellation (AVC) control, pulse density modulation (PDM) control are normally used at SRI for high frequency induction heating. In this paper a new hybrid control technique by combining PSC and PDM is analyzed. The new control technique overcomes the drawback of individual scheme and provides a wide range of power control. The analyses of all the control techniques are verified through MATLAB simulation results
