Abstract

The regulator controls the low-voltage, high-current power requirements of a data processing system. Voltages from one to four volts and currents up to 100 amperes are common. The dual response regulator includes phase control regulator 2 and shunt control regulator 3. Regulator 2, connected to a power source, not shown, delivers power over transmission line 4 and return 5 to loads L1, L2, and L3. These loads are different parts of a data processing system. The voltage across L1 is 1.2 volts to ground. The voltage across L2 is ground to -3 volts. The voltage across L3, therefore, is 1.2 volts to -3 volts. During normal operation, the current drawn by the three loads is rapidly changing. This is because the loads include many circuits which are rapidly changing conduction states at nanosecond and subnanosecond speeds.

Dual Response Regulator

The regulator controls the low-voltage, high-current power requirements of a data processing system. Voltages from one to four volts and currents up to 100 amperes are common. The dual response regulator includes phase control regulator 2 and shunt control regulator 3. Regulator 2, connected to a power source, not shown, delivers power over transmission line 4 and return 5 to loads L1, L2, and L3. These loads are different parts of a data processing system.

The voltage across L1 is 1.2 volts to ground. The voltage across L2 is ground to -3 volts. The voltage across L3, therefore, is 1.2 volts to -3 volts. During normal operation, the current drawn by the three loads is rapidly changing. This is because the loads include many circuits which are rapidly changing conduction states at nanosecond and subnanosecond speeds. Due to the rapid changes in current, regulation is required to maintain the load voltages.

In order to maintain the load voltages, regulator 2 senses the voltage across L2 via lines 6 and 7 and adjusts such regulator so as to maintain the output across lines 4 and 5 at a constant potential difference. Since regulator 2 works on a phase control principle, it is inherently slow, when evaluated with reference to nanosecond speeds, in responding to load changes. Regulator 2, therefore, tends to supply the average current required by the loads. Although the sense inputs for regulator 2 are across L2, any part of or the total load ca...
