LLC Resonant Inverter

The LLC converter is a resonant inverter with three reactive components where the DC input voltage revolves into a square wave by a switching grid organized as either a half-or full-bridge to sustain the resonant LLC tank that effectively filters out harmonics yielding a sinusoidal like voltage and current waveform. This in effect sustains a transformer that gives voltage scaling and primary-secondary isolation. The converter power flow is dominated by modulating the square wave frequency with respect to the tank circuit's resonance. It is based on resonant current oscillation. It is also known as a DC to DC converter or DC to AC inverter. The main function is to reduce the switching losses of the devices. Heavy-duty power supply units in the range of 200 watts 1000 watts require LLC resonant inverter. Shah electronics manufacturers ferrite transformer and steroidal coils for LLC resonant inverter. The main element of power applications that Shah Electronics designs are mainly ferrite coils, however, it also supplies telecom power. Shah electronics has also provided fast, reliable, and enthusiastic service to all the consumers during development production and follow-on support.
