The invention discloses a high voltage power supply equipment power-on sequence control circuit which comprises a DSP circuit, a primary reset circuit and a secondary reset circuit. The output of theprimary reset circuit is connected with the DSP circuit and the secondary reset circuit. The primary reset circuit and the secondary reset circuit are realized by using a reset chip. After the primaryreset circuit reaches the working voltage, the high level is delayed to generate, the low level in the delay time enables the DSP circuit to enter the hardware reset state and the secondary reset circuit maintains the reset state. When the primary reset circuit outputs the high level, the primary reset circuit completes resetting. The secondary reset circuit delays generation of the high level when the primary reset circuit completes resetting. The accurate control of the power circuit requiring strict sequence control unit can be realized by the two reset circuits and the enabling logic combination circuit.
