The invention discloses a solar array regulator which comprises k stages of power units sequentially controlled by a hysteresis comparator, the input ends of the k stages of power units are connected to a solar array section, and the output ends of the k stages of power units are connected to an HV-BUS high-voltage bus and a main error amplification circuit in parallel. The power unit comprises a shunting part, a DCX push-pull part and a hysteresis comparator, the hysteresis comparator receives a signal of the main error amplification circuit, the DCX push-pull part is used for amplifying an input voltage in an equal proportion according to the turn ratio of a transformer, and control is carried out through the shunting part, the hysteresis comparator and the main error amplification circuit. According to the invention, the SADA can be ensured not to generate high voltage, the power supply safety of the whole satellite is protected, and the power density of the PCU is improved.
