Beschreibung
Zusammenfassung:	The invention discloses a radio-frequency oscillating wave superposed pulse power supply for electrical discharge machining, and a control method thereof. The power supply is characterized in that an oscillating wave frequency control unit is connected with a first direct current (DC) voltage-stabilized power supply, and the oscillating wave frequency control unit is powered by the first DC voltage-stabilized power supply, and used for generating a required sine wave oscillation signal in a frequency range from MHZ to GHz; an oscillating wave amplitude control unit is connected with a second DC voltage-stabilized power supply and the oscillating wave frequency control unit, and the oscillating wave amplitude control unit is powered by the second DC voltage-stabilized power supply, and used for amplifying the sine wave oscillation signal to an actually required oscillation amplitude; and an oscillating wave superposition unit is connected with the oscillating wave amplitude control unit, and used for superposi
