Embodiment
[0037] Example: see figure 1 , figure 2 , in the present invention, the output voltage is taken as the control target, and the phase lead angle is adjusted in real time according to the situation of the output voltage. In simple terms, when the voltage is too high, the phase lead angle is increased, and when the voltage is low, the phase lead angle is decreased to achieve a constant output voltage. The specific plan is as follows:
[0038] A current phase control voltage regulator comprises a single-chip MCU, a MOS tube, a battery voltage sampling circuit, an output current sampling circuit, a phase line current sampling circuit, and a Hall position sensor. in:
[0039] There are 6 MOS tubes, which form a three-phase full-bridge rectifier circuit; the single-chip MCU is connected with the MOS tubes through a MOS driver, so as to energize and commutate the output phase lines of the magneto (for example, from the state of A phase energization to B phase connection) state of...

The invention discloses a current phase controlling type voltage regulator which comprises the components of a single-chip microcomputer MCU, an MOS tube, a battery voltage sampling circuit, an outputcurrent sampling circuit, a phase wire current sampling circuit and Hall position sensors. The single-chip microcomputer MCU is connected with the MOS tube through an MOS driver, thereby performing energizing and phase commutation on the output phase wire of a magnetic motor. The output current sampling circuit and the phase wire current sampling circuit are respectively used for sampling the output current of a three-phase full-bridge rectifying circuit and the phase current of the magnetic motor. The battery voltage sampling circuit is used for acquiring voltage of a storage battery. ThreeHall position sensors are arranged. A Hall signal which is detected by the Hall position sensor is transmitted to a level converting circuit and then is transmitted to the single-chip microcomputer MCU. The current phase controlling type voltage regulator has advantages of effectively reducing heat generation, oil consumption and noise, improving efficiency, improving output voltage controlling precision and realizing high reliability.
Description
technical field [0001] The invention relates to the technical field of engine starting controllers, in particular to a current phase control voltage regulator. Background technique [0002] The existing motorcycle power generation system is a permanent magnet motor + a voltage regulator. The motorcycle voltage regulator is divided into a short-circuit type and a switch type. The short-circuit type consumes a lot of power and loses the output power of the engine, which affects the speed-up performance and increases fuel consumption. The switching type has the problems of high noise and large friction torque, and is prone to runaway, shortening the life of the battery and even burning the body load; and both use thyristors as power devices, which generate high heat and low efficiency. Contents of the invention [0003] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to solve the problems of high heat generation, low effic...
