Effect of leakage inductance on solar panel based multiple output inverter for induction heating system.

This paper focuses on the simulation of solar panel-based multiple output inverter including leakage inductance. The solar panel is used as the energy source and it is connected to a flyback converter to boost the voltage. The voltage output of the photovoltaic panel is boosted to 181.6 V from 16.5 V DC using an interleaved fly-back converter. Half-bridge multiple output inverter is used to produce alternating current in multiple coils. Using this circuit topology multiple loads can be heated simultaneously. All three coils are connected in parallel. If one coil is damaged then other coils will be able to provide the desired output. A wide range of output is studied in terms of current gain. In this proposed circuit two IGBTs have been used as semiconductor switches. Two freewheeling diodes are connected parallel to the IGBTs to provide the discharging path of the energized coils. Current variation through the coil is possible by varying the duty cycle. A simple asymmetrical duty cycle control strategy is used to vary the duty cycle. The available range of current is 2.18–2.43 A. [ABSTRACT FROM AUTHOR]
