Multi-element self-sensing technology-based ripple suppression type driving power supply for cruise system

Abstract

The invention discloses a multi-element self-sensing technology-based ripple suppression type driving power supply for a cruise system. the driving power supply mainly comprises an adjustment chip U2, a diode rectifier U1, a triode VT1, a triode VT2, a polar capacitor C3, a diode D2, a voltage detection circuit, a constant-current driving circuit, a ripple suppression circuit connected between the negative output end of the diode rectifier U1 and the voltage detection circuit in series, a micro-processing circuit connected between the collector electrode of the triode VT1 and the constant-current driving circuit in series, and the like. According to the technical scheme of the invention, the leakage current and the loss current of the output current can be effectively reduced. Meanwhile, the magnetic biasing phenomenon, generated due to the unbalanced driving waveform of an output voltage, can be inhibited or even eliminated, so that the output driving voltage is kept consistent with a reference voltage. Therefore, the output voltage is more stable and more accurate. As a result, the output voltage and the output current are ensured to be stable.
