Design Idea for a simple gated-osciallator circuit to limit MOSFET on-time using an An R-C time to limit On-time pulse period length and generates its own maximum permitted On/Off duty cycle. A power ...

Fig. 1: The silicon-controlled rectifier One major aspect of development in broadcast transmitter technology and power electronics is in the area of power control. On the traditional transformer, we ...

As electronics applications continue to become more compact, powerful, and versatile, the final system demands and complexities of mobile and stationary devices also are becoming increasingly ...

The transformation of the power landscape involves more than just generation. The distribution of electricity is being changed as well, with technology designed to make electrical systems safer, more ...

While DSPs are the primary controllers in uninterruptible power supplies (UPS) with power-factor correction (PFC), ac generation and battery management, microcontrollers serve secondary functions for ...

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 ...

With any low-power design, the designer has the choice between choosing low-power components or switching off the power to peripheral devices. When considering the choice of non-volatile flash ...
