AC-DC Converter

Traco Power released a new TRI series of DC/DC converters offered in compact DIP-24 (3-10 Watt) or 2”x1” (15-20 Watt) packages. The TRI line features a sophisticated reinforced isolation system which is able to withstand high test voltages (9000 VDC for 1s and 5000 VAC for 60s) and working voltages (1000 VACrms). Complementing this isolation feature is a high Common Mode…

Power Integrations launched new members of its InnoSwitch™3 families of offline CV/CC flyback switcher ICs features up to 95% efficiency across the full load range and up to 100 W in enclosed adapter implementations without requiring a heatsink. The increase in performance is achieved with the help of an internally developed high-voltage GaN switch technology. Newly released…

In the previous tutorial, we saw how a Dual Power Supply Circuit is designed. Now, we learn about Dual Converters, which can convert AC to DC and DC to AC at the same time. As the name suggests, Dual Converter has two converters, one converter works as a rectifier (Converts AC to DC) and the other converter works as an inverter (converts DC into AC). Both converters are…

In the modern era, almost every household electronics works on Direct Current (DC) but we get Alternating Current (AC) from power generation plants via transmission lines becuase AC can be transmistted more efficiently than DC in lower cost. So every appliance which works on DC has and AC to DC converter circuit. We previously built a 5v cell phone charger which also…

There are lots of factories and plants in the world which use a different type of high power motors. Due to the high power consumption, the factories and plants end up paying a high amount of energy bills. To overcome the high power consumption and to increase the efficiency, VFD was introduced four decades ago but the circuitry was not strong enough.

MORNSUN released two new AC/DC Converters, LHE40-20Bxx and LHE60-20Bxx series that offers high isolation of 4000VAC and compatible with their first generation series LH40-10Bxx and LH60-20Bxx AC/DC converters. With these two, the entire LHE series of AC/DC converters now provide powers of 5W, 10W, 15W, 20W, 40W and 60W.

Now engineers designing into applications in factory automation, medical, communications and consumer markets can tap into four new micro-system-level IC (“uSLIC™”) modules from Maxim Integrated. The MAXM17552, MAXM15064, MAXM17900 and MAXM17903 step-down DC-DC power modules join Maxim’s extensive portfolio of Himalaya power solutions, providing the widest input voltage…

Vicor Corporation announced a new 3-phase, AC-DC converter module (“RFM”), capable of delivering 10kW of regulated 48VDC in a power tablet configuration measuring 9.4 x 5.9 x 0.6in (24 x 15 x 1.5cm). The RFM™ provides a power-factor-corrected, regulated, and isolated DC output with integrated filtering and built-in fault protection for redundant operation…

After the success of the recently released RAC05-K/277 5W AC/DC series, RECOM now added new output options to this product series. The RAC3.5-K/277 versions supply up to 3.5W on the PCB, while the RAC05-K/277/W wired versions simplify installation.

The 3.5W and wired 5W modules perform reliably in harsh environments…

MORNSUN adds 85-305VAC cost-effective AC/DC converters series LDE02-23Bxx to its LDE series portfolio, which is compatible with the previous LD02-10Bxx series and comes with higher isolation voltage and better operating temperature range. With this LDE02-23Bxx series addition, now the entire LDE series provide powers of 2W, 3W, 5W, 6W, 10W, 15W and 20W.
