| Abstract: | A current/voltage supply is presented based on the technology of PWM. It adopts SSRas the shunt. It can convert the current supply variable from several amperes to several hundredamperes to a voltage supply with low heat rate and stable output voltage. This power supply isespecially adapted to be used as the power supply for measure system of a high voltage side. Theoperating principle of the circuit and the pivotal technology are analogized, the experimental resultsare also given. |
