Single-phase power factor correction (PFC) circuits—a kind of front-end AC/DC converters—are ubiquitous in a variety of consumer electronic devices ...
When model-based multivariable control made its debut in the 1980s, it was expected that process models, once acquired through a plant step test, would be durable and long lived. However, this ...
The 1/16 DIN panel size SOLO basic controller operates on 100 to 240 VAC 50 / 60 Hz input power. Two 4-character 7-segment LED displays indicate process value (PV) and setpoint value (SV); red for PV ...
Among all power factor correction (PFC) topologies, totem-pole bridgeless PFC provides the best efficiency; therefore, it is widely used in servers and data centers. However, closing the current ...
The ISL6545 and ISL6545A from Intersil are single-output PWM controllers. These devices integrate the MOSFET drivers, boot diode and current-sensing functions on a single chip. The ISL6545 and ...
