摘要： A power converter converts a medium-voltage output from a solar module to an appropriate voltage to power a solar tracker system. The power converter includes a voltage divider having at least two legs, a first semiconductor switch subassembly coupled in parallel with a first leg of the voltage divider, and a second semiconductor switch subassembly coupled in parallel with a second leg of the voltage divider. The power converter may be a unidirectional or a bidirectional power converter. In implementations, the signals for driving the semiconductor switches of the first and second semiconductor switch subassemblies may be shifted out of phase from each other. In implementations, if the bus voltages to the semiconductor switches are not balanced, the pulse width of the driving signal of the semiconductor switch supplied with the higher bus voltage is decreased for at least one cycle.

摘要： A voltage regulator which provides an output current at an output voltage at an output node of the voltage regulator, based on an input voltage at an input node of the voltage regulator is described. The voltage regulator has an output amplification stage for deriving the output current at the output node from the input voltage at the input node in dependence of a drive voltage. Furthermore, the voltage regulator has a differential amplification stage to determine the drive voltage in dependence of the output voltage and in dependence of a reference voltage. In addition, the voltage regulator has an adaption unit to determine a capacitance indication of a capacitor value of an output capacitor coupled to the output node of the voltage regulator. The adaption unit also adapts the differential amplification stage in dependence of the capacitance indication.

摘要： The present disclosure relates to the technical field of semiconductors, and discloses a low dropout regulator (LDO) circuit. The LDO circuit includes a first adjustment pipe, a second adjustment pipe, a first error amplifier, and a second error amplifier. The first adjustment pipe is connected between an input end and an output end of the LDO circuit. The second adjustment pipe is connected between the output end of the LDO circuit and the ground. The first error amplifier includes a first input end and a second input end, where the first input end is connected to the output end of the LDO circuit, and the second input end is used to receive a reference voltage. The second error amplifier includes a third input end and a fourth input end, where the third input end is connected to the output end of the LDO circuit, and the fourth input end is used to receive the reference voltage. In a case in which an output voltage outputted by the output end of the LDO circuit is smaller than the reference voltage, the first error amplifier controls the first adjustment pipe to be turned on, and the second error amplifier controls the second adjustment pipe to be turned off; and in a case in which the output voltage is greater than the reference voltage, the first error amplifier controls the first adjustment pipe to be turned off, and the second error amplifier controls the second adjustment pipe to be turned on.

摘要： This disclosure describes techniques for generating relatively low regulated power supply voltages over a relatively wide range of input voltages. The techniques for generating the regulated voltages may include using at least two different pass transistors to regulate an output voltage of a voltage regulator. Both the turn-on threshold voltage and the maximum drain-to-source voltage rating of the first pass transistor may be greater than the corresponding characteristics of the second pass transistor. Using two different pass transistors with two different turn-on threshold voltages and two different maximum drain-to-source voltage ratings may increase the range of voltages over which a voltage regulator can generate a relatively low output voltage relative to the range of voltages that would be allowable if a single type of pass transistor were used.
