The invention discloses a voltage source type ice melting device, the device comprises an AC/DC converter, the AC side of the AC/DC converter is connected with an AC power supply, the device further comprises at least two current limiting units, Each current limiting unit is composed of a current limiting resistor and a bypass switch in parallel. The current limiting unit is connected in series. One end of the series connection is connected with the DC positive electrode or the negative electrode of the AC/DC converter, and the other end is used as the DC output port of the device. The invention also includes a control method and a control device using the ice melting device. The invention realizes the large-scale regulation of the ice melting current through the control of the AC/DC converter and the input of the current limiting unit, solves the problem of small regulation range of the voltage source converter, has the advantages of low cost, high reliability, easy realization and high performance-cost ratio.
