FIELD: high-frequency power supplies for induction heating. ^ SUBSTANCE: proposed off-line inverter has its backward diode connected in parallel with two pairs of circuits, each being set up of transistor and one of four separate similar-inductance chokes of LC switching circuit. ^ EFFECT: reduced direct switching surges across thyristors caused by abrupt reverse-current drop in backward diode during its turning off. ^ 1 cl, 2 dwg |
