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

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
