The present invention relates to a high power control circuit for a DC motor without a transformer and, more specifically, to a high power control circuit for a DC motor, capable of driving the DC motor by receiving commercial AC power and converting the AC power into DC power without using the transformer. The high power control circuit for a DC motor without a transformer includes an AC input power source to which commercial AC is applied, an input EMI filter part which blocks the noise of the AC input power source, a rectifying unit which rectifies the AC power to the DC power, a constant voltage generating unit which is serially connected to the rectifying unit, a DC-DC converting unit which is connected to the constant voltage generating unit, a position limit setting unit which drives a position limit setting switch of the DC motor, a forward and backward rotation control unit for the DC motor, and a negative voltage switching unit. |
