摘要：A current balancer suitable for a multi-phase power converting device isprovided. The current balancer includes an error detection unit and a plurality of pulsecontrol units. Each of the pulse control units includes a current-to-voltage converter, a
charging and discharging controller, a capacitor, and a comparator. The error detectionunit detects a plurality of channel currents generated by the multi-phase power
converting device, and generates a plurality of error currents by calculating. The chargingand discharging controller provides a charging voltage or a discharging voltage accordingto a constant pulse-width modulation (PWM) signal. When the channel currents arebalanced, the comparator generates a PWM signal with a constant duty cycle. When thechannel currents are not balanced, an error voltage generated by the current-to-voltageconverter is used to adjust a voltage level of the charging voltage or the dischargingvoltage, so that the PWM signal is varied correspondingly.
