摘要： A tester and method for testing a rectifier-regulator. A ramping voltage generator generates a ramping input voltage during each of a multiplicity of ramping cycles in response to ramping voltage control signals provided by a controller. A relay circuit relays the ramping input voltage to one of the input terminals of the rectifier-regulator during each ramping cycle in response to relay control signals provided by the controller. The rectifier-regulator provides in response a ramping output voltage at its output terminal during each of the ramping cycles. A voltage measurement circuit makes voltage measurements during each of the ramping cycles representing the ramping output voltage. A trip point determination circuit determines when the trip point of the rectifier-regulator occurs during each of the ramping cycles and generates in response a trip point signal during each of the ramping cycles indicating that the trip point has occurred. A memory stores a predefined maximum trip point voltage and a predefined minimum trip point voltage. The controller estimates the trip point voltage for each ramping cycle in response to the trip point signal and the voltage measurements. It then compares the estimated trip point voltage for each of the ramping cycles with the stored predefined maximum and minimum voltages and generates a trip point error flag indicating that a trip point error has occurred for each of the ramping cycles where the compared trip point voltage does not fall within a range between the stored predefined maximum and minimum voltages.
