Bidirectional reset integrator converter
Abstract:
A bi-directional reset integrator converter, including a common reset pulse generator operable by input currents of either direction, is disclosed. The reset pulse generator creates a current flow through common components in either direction, the direction depending upon the direction of the input current. Upon receipt of a reset pulse request from the integrator of the converter, the common current flow path is connected to the integrating capacitor of the converter and dumps (or withdraws) a Q = I .sup.. .DELTA.T charge that reduces the magnitude of the capacitors stored voltage. Low asymmetry and good linearity result from the use of common components in the current flow path that provides the capacitor voltage reducing charge. In addition, good scale factor stability is provided by a temperature compensating bridge circuit.
