Many microcontrollers feature a pulse-width-modulated (PWM) output that can be low-pass filtered to produce a variable dc voltage. Without additional circuitry, however, this technique is limited to ...

High voltage batteries power modern EVs but what keeps their control & safety systems running? Can a 4kW DC DC solution ...

In an earlier blog post I did a teardown analysis of the XL4015 DC-DC Buck Converter module. I recently received an improved version of the same module. I purchased it from an online seller in China.

Using voltage data down to the consumer level is essential for grid optimisation and operational flexibility in the new era of intermittent generation and fast-changing user demand. Power grids were ...

With the proliferation of 5G networks, cloud computing, Internet of Things (IoT) and virtualization, IT infrastructure is driving the demand for high-performance computing servers. Each new server ...

The electronics industry is undergoing a clear transition. Products are becoming more integrated, power-sensitive, and performance-driven, placing greater demands on the quality of power used during ...

Variable frequency drives (or VFDs) are widely used throughout industry to provide adjustable speed control of ac motors. Although modern versions are relatively simple to install and operate, VFDs ...

Measuring extremely high dc voltages of 10 kV or more usually requires a suitably equipped high-voltage ohmmeter or a digital multimeter and high-voltage divider, along with the proper safety ...
