High-stability type driving power supply for cruise system based on multielement self-sensing technology

Abstract

The invention discloses a high-stability type driving power supply for a cruise system based on a multielement self-sensing technology. The high-stability type driving power supply mainly comprises a regulation chip U2, a diode rectifier U1, a triode VT1, a triode VT2, a polar capacitor C3, a diode D2, a pulse adjustment circuit, a voltage detection circuit, a constant current driving circuit, a comparison amplifying circuit, a micro-processing circuit and the like, wherein the comparison amplifying circuit is connected between a CS pin and a VM pin of the regulation chip U2 in series; and the micro-processing circuit is connected between the collector electrode of the triode VT1 and the constant current driving circuit in series. By adoption of the high-stability type driving power supply, the leakage current and loss current of the output current can be effectively lowered; magnetic biasing generated by imbalanced driving waveform of the output voltage can be suppressed or eliminated; the output driving voltage and a reference voltage can be kept consistent; and the output voltage can be more stable and accurate, so that it is ensured that the high-stability type driving power supply can output stable voltage and current.
