System Architecture & Signal Flow
The CM300HA-24H integrates two IGBT switches in a half-bridge (dual) configuration. Gate drive signals (typically ±15V) are applied to the G-E terminals of each switch. The collector of the lower switch and emitter of the upper switch form the AC output terminal. A dedicated isolated baseplate ensures the power circuit is electrically isolated from the heatsink/chassis, simplifying system grounding design. Recommended gate resistor range: 1–10 Ω (application-specific tuning required).

Technical FAQ
Q: Is the CM300HA-24H a direct replacement for CM300HA-24E?
A: The -24H suffix denotes the 600V/300A rating variant. Cross-reference your existing module’s datasheet to confirm pin-out and VCE compatibility before substitution.
Q: What gate driver IC is recommended?
A: Mitsubishi M57962L or equivalent isolated gate driver ICs are commonly used. Ensure bootstrap or isolated DC-DC supply provides ±15V with adequate peak current (≥2A).
Q: Can this module operate without a heatsink in bench testing?
A: Only at very low duty cycles and reduced current. Continuous operation without adequate thermal management will exceed Tj(max) and cause permanent damage.
Q: Do you offer quantity pricing for OEM orders?
A: Yes. Contact us at support@konmask.com or call +0086 19859288691 for volume pricing and lead time negotiation.
Q: What is the warranty policy?
A: All modules sold through Konmask.com carry a 12-month warranty against manufacturing defects under normal operating conditions.
