WIDE LOAD MATCHING CAPABILITY POWER SUPPLY |
摘要 |
A high frequency power inverter comprises a power supply (20), a thyristor (SCR5 or SCR6) for switching the energy from the power supply to a load (10) and a neutral capacitor (C3) for storing energy cyclically to assure reverse voltage is applied to the thyristor (SCR5 or SCR6). A clamp circuit (L9, L10, D3, D4) is comprised of an inductor (L9 or L10) having a relatively large value for permitting a gradual leaking of the capacitor voltage during an inverting of the power supply voltage to the load (10) so that the capacitor (C3) can ring-up to a higher value than the supply voltage. The inductor (L9, L10) is selected so that under all conditions, the voltage on the capacitor (C3) will be safely larger than the power supply voltage plus a load voltage peak for a time long enough to assure thyristor turn off. |
