Comparison of two inverters of series intermediate frequency furnace and parallel intermediate frequency furnace

Technical

equipment electrical principle common sense

Series inverter	Parallel inverter
( 1 ) The output voltage is a distance wave	The output voltage is a sine wave
( 2 ) The output current is a sine wave	Output current is a distance wave
( 3 ) The furnace induction coil voltage is reversed Q times the output voltage of the transformer	Furnace induction coil voltage, etc. Inverter output voltage
( 4 ) The induction coil current is equal to Inverter current	Induction loop current is inverter Q times the output current
( 5 ) Stabilizing DC voltage with DC a large capacitor is connected in parallel	Constant DC current Serially connected large filter inductor
( 6 ) Using a high voltage compensation capacitor	Use standard compensation capacitors
( 7 ) Using a feedback diode	Do not feedback diode
