Power supplies do not require preheat or ignition but do require a soft-start. The resonant topologies are different but both are driven by a half-bridge and controlled by frequency. Also, power ...

The initial family of GaNSense Half-Bridge ICs includes the NV6247 which is rated at 650 V, 160 mOhms (dual), and the NV6245C, rated at 275 mOhms (dual), both in an industry-standard, low-profile ...

Gate-drive pulses switch the half-bridge MOSFETs with a 50% duty cycle. The resulting square wave is applied to the primary winding of a transformer. The transformer usually steps the voltage down.

The power supply that [Ken Shirriff] ... In this circuit, the Thyratrons are used as half-wave rectifiers that can be rapidly switched on and off by a feedback circuit.

Fig. 2. Ideal diode emulators improve efficiency in flyback converters. A (top) shows the circuit and b (bottom) shows the waveforms. In Fig. 2, the current direction and amplitude is detected by ...

In control applications, operational power supplies are alternatives to other sources, ranging from simple SCR bridges used in electric drills to elaborate servoamps.

GaNSense half-bridge ICs are anticipated to have a significant impact in all Navitas target markets including mobile fast chargers, consumer power adapters, data centre power supplies, solar inverters ...

This power supply could power a 555 oscillator driving an LED. Another test used C ac =0.22µF, R1=10kO, R2=470O, R B =470O, C F =470µF, and Q1=BC549. This could be used to build a zener-transistor ...

AOS has announced a 50W coil-driver for wireless charging transmitters. AOZ32034AQV is a half-bridge, designed to be used in full-bridge circuits driving a resonant tank circuit. “A key feature of ...
