The invention discloses a wave splicing power regulating device based on MOSFET (Metal-Oxide -Semiconductor Field Effect Transistor). The conduction angle alpha is regulated to vary in the range of 0 to pai according to required power, so that the continuous regulation of output voltage from the second level of voltage to the first level of voltage, and the regulation of power required by power utilization equipment is realized. Because each group of insulated gate field effect transistors includes a forward insulated gate field effect transistor and a reverse insulated gate field effect transistor connected in series, after each group of insulated gate field effect transistors is turned off, an output circuit formed from intrinsic diodes in series back-to-back is formed, the transistors can not be conducted to form a return circuit. Thus, the influence of intrinsic diodes in parallel back-to-back between a drain electrode and a source electrode caused by the structure of the insulated gate field effect transistors is overcome, short circuit caused by simultaneous output of two levels of secondary circuits is avoided, and MOSFET can be applied to the wave splicing power regulatingdevice.
