摘要： A control circuit and control method for a power converter detects change of the output voltage of the converter, and performs the time-optimal control function when the change exceeds the default value. According to the voltage slew rate detected at the time of the change exceeding the default value, a time interval T1 from the change exceeding the default value being detected to the current of the inductor rising to be the same as the output current of the converter is estimated, and the time intervals T2 and T3 are figured out based on the time interval T1. The parasitic resistance of the output capacitor of the converter is taken into account during estimating process such that even if the output capacitor has larger parasitic resistance, the output voltage can be back to the steady state value accurately to avoid the time-optimal control being triggered repeatedly.

摘要： A multi-phase buck converter has a digital compensator to select a set of compensation coefficients depending on the operating phase number of the multi-phase buck converter, or including different compensators for each operation phase number to improve the loop gain bandwidth, transient response and stability of the multi-phase buck converter. The multi-phase buck converter operates with more phase circuits for higher loading and operates with fewer phase circuits for lower loading. The compensation varies with the number of the operated phase circuits so to be adaptive to the operation condition with an optimized control-to-output voltage transfer function.

摘要： For a multiphase interleaved voltage regulator, an offset cancellation circuit is applied for each phase separately. The current loop gain of each phase is thus increased to mitigate the beat-frequency oscillation in phase currents when the beat frequency is below the bandwidth of the low-pass filter in the offset cancellation circuit, without introducing additional instability issue that is the drawback of increasing current-sensing gain.

摘要： A control circuit and method for controlling a power converter comprises an adder, a digital compensator, and a pulse width modulation circuit. The adder acquires an output voltage difference between the output voltage and the reference output voltage. The digital compensator, which has a Z-domain transfer function, references the output voltage difference to generate a pulse width control signal with the least significant bits of the denominator coefficient in the Z-domain transfer function being regulated to achieve the load line function of the power converter. Further, the pulse modulation circuit is controlled by the pulse width control signal to generate the pulse width modulation signal to control ON/OFF of the power converter.

摘要： An easy LSB tuning method is proposed for a digitally controlled DC-DC converter to increase the DC gain of the digitally controlled DC-DC converter under conditions of no-limit-cycle and a finite bit number to reduce steady-state error of the digitally controlled DC-DC converter. The LSB of one or more of the coefficients in the denominator of the discrete-time domain transfer function of the digital compensator in the digitally controlled DC-DC converter is so tuned that the sum of all coefficients in the denominator of the discrete-time domain transfer function becomes zero. Therefore, the influence of round-off effect on the coefficients of the digital compensator is mitigated.

The motor controller includes a plurality of pins but does not include a dedicated pin for transmitting a clock signal and a dedicated pin for transmitting a motor specification database setting signal, wherein the clock signal and the motor specification database setting signal are for setting motor specification data. The clock signal and the motor specification database setting signal are transmitted through two of the plural pins which are multi-functional function pins shared by other functions in a normal operation mode. In a motor specification database setting mode, these multi-functional function pins are used for transmitting the clock signal and the motor specification database setting signal. In the normal operation mode, these multi-functional function pins are used for other functions.

摘要： A multi-phase motor control method controls a multi-phase motor which includes multiple nodes respectively receiving a corresponding number of driving voltage signals to control a rotation of a rotor. The motor control method includes: sensing a signal phase of a current signal corresponding to at least one node, for example by sensing a zero-crossing point of the current signal; determining a reference phase for the current signal; calculating a phase difference between the signal phase and the reference phase; and controlling a phase switching frequency of the stator according to the phase difference, such that the signal phase is close to or in phase with the reference phase, to thereby obtain an optimum rotation speed of the rotor corresponding to a given driving voltage. The present invention also provides a multi-phase motor control device using the motor control method.
