Abstract
An electric stove having a single free-zone burner includes: a controller which outputs a first output signal including a first output level signal and a first synchronization signal, and a second output signal including a second output level signal and a second synchronization signal; a first inverter which successively receives the first output signal and second synchronization signal, and outputs first high-frequency power to a first working coil; and a second inverter which successively receives the first synchronization signal and second output signal, and outputs second high-frequency power to a second working coil. The first inverter and second inverter simultaneously output first high-frequency power and second high-frequency power when the first synchronization signal and second synchronization signal are both received.
