Description

technical field [0001] The invention relates to the field of power supply testing, in particular to a power conversion circuit for a power module of a power analyzer. Background technique [0002] Usually, when conducting tests related to DC power supplies, engineers must assemble and configure multiple instruments to complete the DC power supply and measurement tasks. When performing these complex tasks, multiple test instruments may be connected at the same time, thereby increasing the risk of errors; for this reason, engineers may choose automatic testing that is far more complicated than manual testing, but automated testing tasks will reduce manual errors, but writing and debuggers add further workload to already overworked R&D engineers. The emergence of DC power analyzers avoids the need for engineers to use multiple devices and perform complex debugging before testing. The power analyzer can measure the current flowing into the DUT through its built-in current dyna...
