Abstract:
A power supply Active Bleed Voltage Balancing Circuit comprising:a power supply having at least a first output providing a first output voltage at a first output node and a second output providing a second output voltage at a second output node, each output voltage having a respective acceptable range measured with respect to a reference potential, an inductor having a first and second terminal, the inductor first terminal being coupled to the first output node, an oscillator for providing a sequence of control signals having a substantially fixed period, each control signal having a first state during a first time interval followed by a second state during a second time interval, semiconductor switching means responsive to the control signals for alternately switching the inductor second terminal to the second output node during the control signal first time interval and for disconnecting the second terminal from the second output node and connecting the second terminal to the reference potential for the control signal second time interval.
