In vehicle electrical systems, a high- to low-voltage DC/DC converter is a reversible electronic device that changes the DC from the vehicle’s high-voltage (400 V or 800 V) battery to a lower DC ...

We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop? Analog VOM’s attempt to measure resistance of ...
