Pulse Automatic Control TRIZ Cases
- Double Synchronous Virtual Oscillator Control for Grid Converters
A double synchronous unified virtual oscillator controller manages grid synchronization without phase-locked loops.
- Power Converter Feedback Terminal Parameter Setting
A power converter controller uses a sample-and-hold circuit to generate a programming voltage for parameter setting.
- Switching Converter Clock Modulation for EMI Reduction
A switching converter uses a modulated basic clock to vary carrier frequency and optimize electromagnetic emissions.
- Robust Phase-Lock Detector Using Dual-Path Signal Analysis
A phase-lock detector combines sum frequency and baseband component analysis to verify signal presence and phase relationship.
- Clock Doubler Duty Cycle Correction Circuit
Dual charge pumps in a clock doubler detect and correct current mismatches to maintain a 50% duty cycle without running the oscillator at twice the frequency.
- LC-VCO Circuit with Varistor Capacitance for Wide Frequency Range
A voltage-controlled oscillator circuit uses a varistor capacitance circuit to control oscillation frequency through variable resistance.
- Level Shifter for LCD Source Driver AC DC Voltage
A level shifter generates output signals across two voltage ranges using logic control.
