low frequency induction heating equipment
Good start up performance:IGBT MF induction power supply apply series resonance technology so it can be starts up 100% under any condition.
Less indterface to power grid:Less harmonic current and high power factor,Power factoer remaining 0.95 above during machine running
Low energy consumption: in series resonant circuit,voltage at inductor high and current low so energy loss is very low ;Soft switch technology applied then switch loss is very low
