Due to the widespread availability of highly integrated DC-DC switchmode converter devices, system design engineers no longer have to put much effort into the design of low-power converters for many ...

The phase-shifted full bridge (PSFB) shown in Figure 1 is popular in applications >500 W because it can achieve soft switching on its input switches for high converter efficiency. Although switching ...

Author Mazi Hosseini describes a simple, low-cost, voltage-controlled current source using two op amps that provides a good range of current and maximum load. One challenge in circuit design is ...

For the PDF version of this article, click here. Over the years, power supply designers have been persuaded that current mode is superior to its voltage-mode counterpart. As a result, the major PWM ...
